Ingredients

• 3 medium zucchini
• 2 medium red onion
• 3 tablespoons olive oil
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 3 tablespoons lemon juice
• 0.25 cup fresh basil leaves
• 1 teaspoon honey
• 1 clove garlic
• 1 teaspoon Dijon mustard

Directions

Step 1

Preheat your grill or grill pan to medium-high heat.

Step 2

Wash and trim the ends of the zucchinis. Slice them lengthwise into 1/4-inch thick strips.

Step 3

Peel and slice the red onions into 1/2-inch thick rounds, keeping the slices intact for grilling.

Step 4

In a small bowl, mix 2 tablespoons of olive oil, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. Brush the mixture evenly onto both sides of the zucchini and onion slices.

Step 5

Place the zucchini and red onion slices on the preheated grill. Cook for about 3-4 minutes per side, or until grill marks appear and the vegetables are tender but not mushy. Remove from the grill and set aside.

Step 6

While the vegetables are grilling, prepare the lemon basil vinaigrette. In a blender or food processor, combine the lemon juice, basil leaves, remaining 1 tablespoon of olive oil, honey, garlic (minced), Dijon mustard, and a pinch each of salt and pepper. Blend until smooth and emulsified.

Step 7

Arrange the grilled zucchini and red onions on a platter. Drizzle the lemon basil vinaigrette over the top.

Step 8

Serve warm or at room temperature. Enjoy this simple yet elegant dish as a side, or pair it with grilled proteins for a complete meal.
