Mix the flour with eggs, milk and about 1/2 teaspoon salt to form a smooth dough. Cover and let rest for about 20 minutes.
Cut the peppers into small pieces and the spring onions into rings.
Heat 1 tablespoon of oil and fry the pepper pieces in it for about 5 minutes. Add the spring onions and fry briefly. Season with salt and pepper.
Brush a pan with 1/2 tablespoon of oil. Pour in half of the batter, distribute it well and place half of the vegetables on top. Cover and roast over low heat for 6-8 minutes, then keep warm. Process the rest of the dough and vegetables in the same way.
