Green Bean Casserole

1/4 - 1/2 cups oil
1/4 - 1/2 cups flour
Mushroom powder, to taste
Salt and pepper, to taste
1 package mushrooms, chopped
1 1/2 cups soy milk or regular milk
2 cans green beans, whole
Enough potato chips to cover the casserole dish

Heat oven to 350 degrees. Prepare a casserole dish by greasing it.
Make roux by mixing flour and oil together. Begin to cook on medium heat. A few minutes after you begin to smell the oil and flour cooking, turn off the heat. Add the soy milk and begin to mix until smooth. Turn the heat back on and cook the sauce until it is thick and warm. You may want to add more milk until you get your desired consistency. Add mushroom powder, salt, and pepper. (If you don’t have mushroom powder, follow the Basic Country Gravy recipe in the sauces section).
Fold the green beans and mushrooms into the mixture and warm. Put this into the casserole dish and cook for 30-35 minutes. Add the potato chips to the dish and cook for 15 more minute.
