Prepare the sauce. Spoon the mayonnaise into a small bowl. Peel and grate in the garlic. Season with mustard and the juice of half a lemon. Grate the cheese into the mayonnaise.

Rinse and chop the lettuce. Wash and slice the cucumber. Rinse and slice the tomatoes.

Place the minced meat in a bowl. Season with salt, black pepper, paprika powder and ground cumin.

Lay the tortillas on a baking sheet lined with baking paper. Using a spoon or lightly oiled hands, spread a thin layer of the minced meat mixture on top of each tortilla.

Heat oil in a frying pan. Place a tortilla in the pan, meat side down, and press down lightly in the centre with a spatula. Fry for about 4–5 minutes. Flip the tortilla and continue frying until the meat is cooked through. Repeat with the remaining tortillas.

Fill the tacos with lettuce, cucumber, and tomatoes. Finish with caesar sauce and the remaining cheese. Serve immediately.
