Pesto-Grilled Vegetable Salad with Fresh Herbs and Lemon Vinaigrette

Grilled vegetables

Grilled vegetables have a way of tasting better than their steamed or sautéed counterparts. Their smoky char and concentrated flavors inspired this Pesto Grilled Vegetable Salad — a bright, healthy dish that lets pesto play a subtle supporting role to the roasted vegetables.

This recipe was created to showcase pesto as a background flavor that adds depth rather than overwhelming the other ingredients. It’s simple, fresh, and perfect for warm-weather meals or as a colorful side.

Assorted vegetables

The salad begins with four vegetables: red pepper, green beans, red onion, and red potatoes. (Noticed the theme? Three of the four start with “red” — a happy coincidence.)

Vegetable prep

Prep the vegetables as follows:

  • Red pepper: slice down each side so you get four flat pieces from each pepper.
  • Red onion: peel and slice into 1/2-inch rounds.
  • Green beans: trim the ends and cut into roughly 2-inch pieces.
  • Red potatoes: slice into 1/2-inch rounds.

Prepared vegetables

Place the potatoes, peppers, and green beans in a large bowl. Add 1 tablespoon of pesto, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Toss with your hands until the vegetables are evenly coated. Keep the red onion rounds separate for now — they can become fragile while mixing.

Lay the onion rounds out on a cutting board and lightly drizzle both sides with olive oil, then season with salt and pepper.

Grill the vegetables. A grill pan works well if you don’t have access to an outdoor grill. Cook each vegetable until you achieve dark grill marks before turning. I usually start with the onions and peppers, then move on to the potatoes and green beans.

Note: if you use a charcoal or gas grill, place the green beans in foil or use a grill pan for them so they don’t slip through the grates.

Grilling potatoes and beans

Cook the vegetables to your preference. I like mine with a little bite, but make sure the potatoes are fork-tender before removing them from the heat.

Once grilled, transfer the vegetables to a cutting board. Dice the peppers, potatoes, and onions into roughly 1-inch pieces; the green beans can remain whole or halved depending on preference.

Diced grilled vegetables

Dice 1/2 to 2/3 of a hothouse cucumber into half-moons and chop two tomatoes (optional). Season the cucumber and tomatoes lightly with salt and pepper and add them to the bowl with the roasted vegetables.

Cucumber and tomatoes

Stack about eleven basil leaves, roll them tightly, and thinly slice to create a chiffonade — a pretty, delicate garnish that adds fresh herbal brightness.

Make a simple dressing: squeeze half a lemon (about 1 tablespoon juice) into a small bowl and whisk in 1 tablespoon olive oil. Season with salt and pepper to taste.

Pour the dressing over the warm (or room-temperature) vegetables and toss until everything is evenly coated. Finish by sprinkling the chiffonade basil on top.

Finished salad

Enjoy this colorful, flavorful salad as a side dish, light main, or picnic offering. The grilled vegetables pair beautifully with the subtle pesto and bright lemon dressing.
