The vibrant colors, the smoky aroma, and the explosion of flavors in every bite – this Grilled Red Pepper, Sweet Onion, and Tomato Salad instantly transports me back to those carefree days.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 15-20 minutes
• Total Time: 35-40 minutes
• Servings: 4
• Dietary Type: Vegan, Gluten-Free

Ingredients

• 2 red bell peppers
• 2 sweet white onions, cut into rounds 3/4 inches thick (e.g., Maui, Vidalia, Walla Walla)
• 4 large tomatoes (approximately 2 lb total)
• Olive oil, for coating
• 1 bunch fresh basil, stemmed, coarsely chopped if desired

For garlic-balsamic vinaigrette:

• 2 garlic cloves, minced
• 2 tablespoons balsamic vinegar
• 1/3 cup extra virgin olive oil
• Salt & freshly ground black pepper, to taste

Equipment Needed

• Grill (charcoal, gas, or indoor electric)
• Mixing bowl
• Paper bag (optional)
• Cutting board
• Small bowl
• Whisk
• Platter

Instructions

1. Prepare your grill. If using charcoal, ignite it and wait until the coals are glowing with a light ash coating. For a gas grill, preheat to high heat. Alternatively, preheat an indoor electric grill. Ensure the grill rack is clean and lightly oiled to prevent sticking.
2. Prepare the vegetables. In a large mixing bowl, combine the red bell peppers, sweet onion rounds, and tomatoes. Drizzle generously with olive oil and toss to coat thoroughly. Make sure each vegetable is nicely coated so they will char nicely on the grill.
3. Grill the peppers. Place the red bell peppers directly over the high heat. Grill, turning frequently, until the skins are charred and blistered on all sides. This typically takes about 5-7 minutes. The charring is key to unlocking the peppers’ sweetness and smoky flavor.
4. Steam the peppers (optional). Transfer the charred peppers to a paper bag. Close the bag tightly and let them cool for about 10 minutes. This steams the peppers, making it easier to peel off the charred skin. You can skip this step if you don’t mind a bit of char in the final dish.
5. Grill the onions. Place the sweet onion rounds on the grill. Grill, turning once, until they are grill-marked and partly tender. This should take about 2-3 minutes per side. Be careful not to burn them; you want them to be softened and slightly caramelized. Transfer the grilled onions to a cutting board.
6. Grill the tomatoes. Place the tomatoes on the grill. Grill, turning often, until they are nicely grill-marked, about 3-4 minutes. Be careful not to overcook the tomatoes, as they can become mushy. You want them to be slightly softened and warmed through, retaining their shape and juiciness. Transfer the grilled tomatoes to the cutting board alongside the onions.
7. Prepare the peppers. Once the peppers are cool enough to handle (after steaming in the bag, if you used that method), peel off the charred skin. Cut the peppers open to remove the seeds and stems. Coarsely chop the peppers and arrange them in a mound on a large platter.
8. Chop the remaining vegetables. Coarsely chop the grilled onion rounds. Core and chop the grilled tomatoes. Add the chopped onions and tomatoes to the platter with the peppers.
9. Add the basil. Scatter the fresh basil leaves on top of the grilled vegetables. The basil adds a burst of freshness and aromatic complexity to the salad.
10. Prepare the vinaigrette. In a small bowl, combine the minced garlic and balsamic vinegar. Gradually whisk in the extra virgin olive oil until the vinaigrette is emulsified and smooth.
11. Dress the salad. Pour the garlic-balsamic vinaigrette over the vegetables on the platter and toss gently to coat everything evenly.
12. Season and serve. Season the salad with salt and freshly ground black pepper to taste. Serve immediately or chill for later.

Expert Tips & Tricks

• Choosing the right tomatoes: Ripe but firm tomatoes work best for grilling. Overripe tomatoes will become too soft and may fall apart on the grill. Roma or beefsteak tomatoes are good choices.
• Preventing sticking: Make sure your grill grates are clean and well-oiled before grilling the vegetables. This will prevent them from sticking and make them easier to turn.
• Peeling peppers easily: The paper bag trick is a classic for a reason! It really does make peeling the charred skin off the peppers a breeze. If you don’t have a paper bag, you can also place the hot peppers in a bowl and cover it with plastic wrap.
• Adjusting the vinaigrette: Feel free to adjust the vinaigrette to your liking. If you prefer a sweeter dressing, add a touch of honey or maple syrup. For a more tangy flavor, add a squeeze of lemon juice.
• Spice it up: Add a pinch of red pepper flakes to the vinaigrette for a little heat.

FAQs (Frequently Asked Questions)

A: While it’s best served fresh, you can grill the vegetables ahead of time and store them in the refrigerator. Dress the salad just before serving.
