I didn't have much in the house (again) so I had to come up with something. The only meat we had was bacon... so I thought some kind of pasta would go well. Now this doesn't have egg in it so it's not a true carbonara... but it was yummy!
+1 bag frozen cheese tortellini
+8 bacon strips
+4 garlic cloves, minced
+1 1/4 cups milk
+4 ounces cream cheese
+1/2 cup butter
+1/2 cup grated Parmesan cheese
Cook pasta according to package directions. Meanwhile, in a large skillet, cook bacon until crisp. Remove to paper towels to drain, then crumble. Remove drippings from the pan (leaving just a tad for some taste but not tons of fat) saute garlic until tender. Add the milk, cream cheese and butter; stir until smooth. Stir in the Parmesan cheese and bacon; heat through. Drain pasta; toss with sauce.
