How to Make It
Heat grill to medium-high. Brush the bread with 1 tablespoon of the oil and grill until golden and crisp, about 1 minute per side. Transfer to plates.
Grill the zucchini until tender and slightly charred, 3 to 4 minutes per side.
Toss the zucchini in a large bowl with the basil, red pepper, ½ teaspoon salt, and remaining tablespoon of oil.
Top the bread with the zucchini and ricotta.
