Prepare the sauce. Peel and finely chop half an onion into a bowl. Dice one pickled cucumber and add it in. Mix in the mayonnaise. Season with mustard and paprika powder. Stir and set aside to marinate.

Rinse and tear the lettuce. Wash and halve the cherry tomatoes. Peel and slice the remaining half onion. Slice the remaining pickled cucumber.

Place the tortillas on baking paper. Press a thin layer of minced meat onto each tortilla. Season with salt and black pepper.

Heat a frying pan with some oil. Place the tortilla, meat side down, into the pan and press in the center briefly with a spatula. Fry for about 2–3 minutes. Flip the tortilla over and crumble cheddar cheese on top of the meat. Continue frying until the cheese melts slightly. Cook each tortilla according to these instructions.

Fill the tortillas with lettuce, cherry tomatoes, onion, and pickled cucumber. Finish with the sauce and serve immediately.
