Preheat the oven: Place a pizza stone in the oven and preheat to 500°F (260°C). Allow the stone to heat for at least 30 minutes.
Grill the halloumi: Heat a grill pan or outdoor grill to medium-high. Lightly brush the halloumi slices with olive oil and grill for 1–2 minutes per side until golden grill marks form. Set aside.
Prepare the dough: On a lightly floured surface, roll out the pizza dough to about 12 inches in diameter. Transfer it to a pizza peel dusted with flour or cornmeal.
Build the base: Brush the dough evenly with olive oil. Sprinkle the minced garlic and optional red pepper flakes across the base.
Add toppings: Arrange the grilled halloumi slices evenly over the dough. Scatter roasted red peppers and Kalamata olives across the top. Season with a little salt and pepper.
Bake the pizza: Slide the pizza onto the preheated stone and bake for 10–12 minutes, until the crust is golden and crisp.
Finish with mint: Remove from the oven and immediately top with fresh mint leaves. Drizzle lightly with olive oil.
Serve: Slice and enjoy while warm.
Notes
For a softer bite, replace halloumi with fresh mozzarella, though you’ll lose the unique grilled flavor.
Add thin slices of red onion for extra crunch and sweetness.
This pizza pairs beautifully with tzatziki or a squeeze of lemon juice right before serving.
