Mashed Canned Potatoes With Toppings/Oven Style

Cut the potatoes into slices, then mash with a fork or mixer. On the road I didn't have a mixer.
Add all of the ingredients except the toppings. If you need a little more milk, add.
Grease a 8 or 12 cup muffin pan or raised side square baking pan.
Place mashed potatoes in the pan.
Make dents with a spoon every four inches in the square pan.
Make a dents in each muffin cup.
Preheat oven to 375 degrees.
Cover with foil. Bake 20 to 25 minutes.
Gas ovens seem to be hotter than electric ovens.
Add all toppings in the order given,except the sour cream.
Cover with foil, bake about 5 to 7 minutes.
Let set about 5 minutes covered.
Use a heat resistant spatula to take out of muffin tin or cut into squares from pan.
Add dollop of sour cream if desired. Serve.
Note: If you have precooked hamburger or sausage you may add after the spagetti sauce but use less potato in each muffin cup.
