Preheat your oven to 400°F (200°C).

Slice the red bell peppers into quarters and toss them with olive oil, salt, and pepper. Roast for about 20 minutes.

Transfer roasted peppers to a blender, add garlic and lemon juice, and blend until smooth.

Heat a skillet over medium heat and cook tilapia fillets for 3-4 minutes on each side until golden brown.

Pour the roasted pepper sauce over the cooked tilapia and simmer for an additional minute.

Serve warm with sides like rice or bread.
