Potato, Cheese and Onion Enchiladas

4 medium potatoes, about 2 lbs
12 oz shredded white cheddar cheese
1/2 cup diced green onion
1 tsp salt
16 oz tomato sauce, 2 small cans
1/4 tsp chilli powder
1 tbs oil
1/2 cup water
12 -8 inch tortillas

 Cook potatoes. Mash potatoes into bowl, add 1/2 of the cheese onion, salt and mix.
In a saucepan combine tomato sauce, chili powder, oil and water. Heat to boiling. Simmer for 5 minutes. I take the sauce and put some on the kitchen counter. Also add some sauce in a 13x9 baking dish.  Lay a tortilla on the sauce on the kitchen counter and coat both sides with the sauce. This gets messy. Put 1/2 cup of the potato mixture on each tortilla and roll up. Place in the baking dish. Top with sauce and cheese. Bake for 15 minutes. Serve with salsa and sour cream. The kids love this. Its not too spicy for them.
