2 pounds zucchini or summer squash, sliced lengthwise 1/8-inch thick
1 garlic clove, minced
1/4 cup extra-virgin olive oil
1 teaspoon Dijon mustard
2 tablespoons red wine vinegar
1 tablespoon lemon juice
1/2 cup roughly chopped roasted red pepper (see note)
1 teaspoon Maras pepper flakes, Korean pepper flakes or sweet paprika
Pinch of cayenne
Salt and pepper
1 pint cherry tomatoes, halved and lightly salted
A few fresh oregano leaves and flowers, for garnish, or a few small basil leaves
Parsley leaves, for garnish
Olives, for garnish
Bring a large pot of well-salted water to a boil. Working in batches, blanch zucchini strips for 1 minute, then remove with a spider or slotted spoon and spread on a kitchen towel-lined baking sheet to cool.
Make the dressing: Put roasted red pepper, garlic, oil, mustard, vinegar, lemon juice, Maras pepper and cayenne in a blender and purée until smooth. Transfer to a small bowl and season with salt and pepper. Taste and adjust acidity with a few drops of lemon juice or vinegar.
Arrange zucchini and cherry tomatoes on a platter. Drizzle judiciously with dressing (reserve excess dressing for up to a week) and garnish with oregano, parsley and olives.
