Brush the courgette with olive oil and season with salt and pepper. Add a pinch of oregano.
Heat a griddle pan and cook the courgette pieces for 2-3 mins on each side until lightly charred.
Add the garlic for the last 2 minutes of cooking.
Transfer the courgette and garlic to a plate and arrange the tomatoes between the pieces.
Squeeze some lemon juice over them.
Crumble the feta on top, then drizzle with a drop of olive oil and garnish with mint leaves.
Serve warm or at room temperature.
