For best results, ensure the grill is hot before adding vegetables to achieve perfect grill marks. Don't overcrowd the grill. If you don’t have a grill, a grill pan or oven roasting at 425°F (220°C) works well. Adjust garlic and vinegar amounts to taste. To make vegan, omit feta or use plant-based cheese. Add protein like chickpeas or grilled chicken if desired. Store leftovers in an airtight container in the refrigerator up to 3 days; add extra olive oil or vinegar before serving if dry.
