Finely chop the onion, place it in a microwave-safe bowl, cover with plastic wrap, and heat at 500W for 3 minutes. Let it cool.

Mix the ingredients marked with ● together and let them blend.

Combine the cooled onion, breadcrumb mixture, ground meat, salt, and pepper, and knead well.

Wash the bell peppers, dry them thoroughly, and cut them in half. Remove only the seeds, keeping the stems intact.

Place the bell peppers and flour in a plastic bag, shake well to coat evenly.

Stuff the bell peppers generously with the meat mixture, mounding it on top.

Heat oil (not listed in ingredients) in a frying pan, place the peppers meat-side down, and sear until browned.

With the meat side still down, add the combined ★ ingredients, cover, and steam. Remove the lid and reduce the sauce.
