In a large non-stick pan sauté beef over medium heat, breaking up with a spoon, until no longer pink – about 5 minutes. Drain off fat in a colander with running water and return to the pan.
Add pureed tomatoes, 4 teaspoons of taco seasoning mix (from recipe above), pumpkin, black beans and simmer until thick - approximately 20 minutes.
Meat mixture can be transported home and put in the refrigerator until dinner time. You should reheat meat first before filling shells.
Add warm meat mixture to the taco shells and sprinkle with cheese.
Bake at 325 degrees for approximately 10 minutes.
Then add your desired toppings and enjoy!!
sour cream, salsa, diced tomatoes, fresh cilantro and avocado or guacamole.
