Shape meatloaf into a heart and put in a glass or ceramic dish.
Pour half of enchilada sauce on top and around the meatloaf.
If you are using a conventional oven, preheat oven to 350 degrees F and bake for 1 hour.
Sprinkle cheese on top and bake for 3 more minutes.
Lightly heat the rest of the enchilada sauce and serve on the side of the Taco Meatloaf, along with sour cream, guacamole and salsa.
Notes
I use and Advantium® GE profile microwave, if you have one, Set oven to U=4 L=4 M=6 and cook for 30 minutes. If using a conventional microwave I would guess medium power for about 30 minutes.
