Take the strudel pack out of the fridge and put it aside. Pour beans into a sieve, rinse and drain. Peel onion and garlic and dice finely. Heat 2 tablespoons of oil, fry the minced meat in it until crumbly.
Add onion and garlic and fry briefly. Add the sauce and beans, simmer for 5 minutes at low heat. Remove the strudel dough from the packaging and unroll. Carefully separate the dough sheets.
Cut the dough sheets in half, place 1/2 sheet in each of 10 wells of a muffin tin (12 wells). Brush with some oil. Place a second sheet of dough on top of each. Season chili con carne with salt, pepper and paprika and distribute in the hollows.
Brush the protruding dough sheets with oil. Bake in the preheated oven (electric range: 200 °C/ convection oven: 175 °C/ gas: level 3) on the lower rack for 8-10 minutes. Carefully remove the muffins from the trays.
Spread the sour cream and cheese on top. Dust with paprika powder. Garnish with marjoram.
