Here's my dairy free version of the pie:
1/4 cup butter (earth balance soy/dairy free butter)
2/3 cup Almond Milk
1 package Taco Bell seasoning mix
2 1/2 cups mashed potato flakes (or left over mashed potatoes-omit butter & milk)
1 pound ground beef or Turkey
1/2 cup chopped onion
1/2 cup salsa
1 cup shredded lettuce
1 medium tomato, diced
1 cup shredded cheddar cheese (tofutti or skip the cheese)
Tofutti Sour cream, optional
Preheat oven 350F.
In a medium sauce pan, melt butter & Add milk, 2 Tbs taco seasoning, mixing well.
Remove from heat, add potato flakes, mixing until incorporated.
Press mixture into the bottom of a regular pie plate, then Bake the "crust" for 7-10 minutes until it just BARELY turns golden brown. In the meantime, cook beef & onions in a skillet until beef is browned and cooked through. Drain. Add Salsa & remaining taco seasoning. Cook until bubbly.
