Spread the tortilla chips on a baking sheet, sprinkle the shredded mozzarella cheese over the top and in the middle, and put it in the oven for a few seconds to melt the cheese. (It burns easily, so watch closely.)

While the cheese is melting, cook the ground beef in a skillet. (I added a splash of tomato sauce.)

In a skillet over medium heat, pour in a little heavy cream and add the cheddar cheese slices. Stir slowly, adding more cream as needed, but don’t overdo it. The sauce should be somewhat thick, not too runny.

Make the guacamole: Dice the onion and tomato into very small cubes. Cut open the avocados and mash them with a fork until smooth. Add the onion and tomato and mix well. Finally, add the salt and squeeze in the juice of half a lime.

Combine everything on the main plate.

Enjoy!
