Bean Cheese Casserole

I found this recipe originally in how it all vegan and modified it to my taste.

Preheat oven to 400 degrees f.

In a large pot of water , boil the sliced potatoes until they can be pierced easily with a fork.

Meanwhile , in a small bowl , stir together the bustard , beans , tomatoes , onion , and pepper , and set aside.

Drain the potatoes and place half of them into a lightly oiled casserole dish.

Add half the bean mixture on top , then half the cheese.

Repeat.

Cover and bake for 35-40 minutes.
