Grilled Eggplant & Summer Squash Salad

Place vinegar in a small saucepan; bring to a boil over high heat. Reduce heat to maintain a simmer; cook, stirring occasionally and watching carefully to prevent burning, until syrupy and reduced to about 2 Tbsp., 12 to 15 minutes. Transfer to a small bowl and let cool.

Meanwhile, preheat grill to medium-high.

Slice eggplant, yellow squash, and zucchini diagonally into 1/4-inch slices. Toss with 7 Tbsp. oil, salt, and pepper in a large bowl.

Grill the vegetables until tender and grill-marked, 2 to 5 minutes per side. Arrange on a platter.

Drizzle the vegetables with the remaining 1 Tbsp. oil and the reserved balsamic syrup. Top with olives and basil.
