In a bowl, combine ground pork, grated mozzarella cheese, finely chopped red onion, finely chopped red pepper, refried beans, finely chopped Thai chili, and dried chili flakes.

Season the mixture to your taste with salt and pepper.

Divide the chili mixture evenly between the flour tortillas.

Fold in the sides of each tortilla.

Roll up each tortilla tightly to form a chimichanga.

Heat vegetable oil in a large, deep frying pan to 350°F (175°C).

Carefully place the chimichangas in the hot oil.

Fry for 3-4 minutes per side, until lightly golden brown and cooked through.

Remove the chimichangas from the oil and drain on paper towels.

Serve immediately with sweet chili sauce.
