2 (6 ounce) cans cream-style frozen green peas
1 (3.5 ounce) package cream cheese, softened
1 cup milk
1 onion, minced
1 green bell pepper, chopped
3 slices Swiss cheese
1 pound shredded mozzarella cheese
1 (10 ounce) can sliced mushrooms, drained
2 tablespoons mayonnaise
2 tablespoons chicken bouillon granules
Preheat oven to 375 degrees F (190 degrees C).
In a large bowl, combine the peas, cream cheese, milk, onion, green bell pepper, Swiss cheese, mozzarella cheese, mushrooms, mayonnaise, chicken bouillon and mushrooms until fully coated. Mix all well.
Transfer peas, cream cheese mixture and bell pepper mixture into a 2 quart casserole dish. Spread the remaining cream cheese mixture over the top. Sprinkle remaining mushrooms over the top.
Bake in preheated oven for 10 to 15 minutes to melt cheese, but do not brown.
