Cut and toast your baguette slices. Smear each piece with 1 Tbsp of goat cheese and top with a slice of tomato. Set aside.
Preheat grill to high heat.
Cut the zucchini into 12 diagonal slices. Toss the zucchini in 2 Tbsp of olive oil or mayonnaise. Salt and pepper, then place on the grill for 2-3 minutes per side, or until grill marks appear and the zucchini is tender. Remove from grill and allow to cool slightly before cutting the slices in half, lengthwise.
Arrange the zucchini halves on top of the toasts—you can use a toothpick if needed. Drizzle with balsamic gaze and garnish with fresh basil ribbons!
