Boil pasta in lightly salted water. Remove from heat when done, drain and set aside. (Do NOT rinse)

Cook meat, either bacon or beef if you are making the meat version. Set aside once cooked.

In a saucepot, melt butter and slowly whisk in flour to get 'paste-like' consistency'.

Slowly add milk or cream then add shredded cheese and continue to whisk until there are no lumps and it has become cheese sauce.

Add drained pasta to cheese sauce and mix well.

For the beef add the meat now or for the bacon version, add beacon and jalapenos.

Mix well then bake in oven in a baking dish, covered at 350F for 15 minutes. Let stand once baked for 5 minutes
