Preheat your oven broiler to high or heat a grill pan over medium-high heat.
Brush both sides of each sourdough slice with olive oil, then toast under the broiler or on the grill pan for 2–3 minutes per side until golden and crisp.
While the bread is still warm, rub the cut side of the garlic clove across each slice.
In a non-stick skillet over medium heat, fry or poach your eggs to your preferred doneness — about 3–4 minutes for a runny yolk.
Spread a generous layer of ricotta on each toast slice.
Top with cherry tomatoes, a fried egg, fresh basil, and a drizzle of balsamic glaze.
Finish with salt, pepper, and a pinch of red pepper flakes if you like a little heat. Serve immediately!
