Ingredients

Instructions

  1. Step 1: In a small bowl, combine 1/4 cup mayonnaise, 2 tbsp chopped basil, 2 tbsp chopped parsley, and 1 minced garlic clove; mix well to create herb aioli.
  2. Step 2: Preheat a grill pan over medium-high heat and brush 1 small thinly sliced zucchini with 1 tbsp olive oil; grill for 2 minutes per side until tender and slightly charred.

  4. Step 4: Toss 1 cup mixed baby greens with 1 tbsp olive oil, 1 tbsp lemon juice, salt, and black pepper to taste.
