Preheat oven to 500 F degrees.
In a large skillet cook the ground beef until it's no longer pink. Add cumin, chili powder, salt and mix.
Add garlic and chorizo sausage and cook for another 5 minutes.
On a pizza tray start with a layer of nachos. Top with half the meat mixture and top 1 cup of cheese and half the jalapeno pepper. Repeat with another layer of nachos, meat, cheese and jalapenos.
Bake for 5 to 10 minutes or until the cheese has melted.
