Preheat oven to 350 degrees Fahrenheit.

Combine black soybeans and green peas in a food processor.

Puree the soybeans and peas until smooth.

Add onion, leek, eggs, sherry, bacon grease, garlic powder, and soy flour to the food processor.

Continue to puree for about one minute until well combined.

Pour the mixture into a bowl.

Stir in the shredded mozzarella cheese.

Pour the mixture into a buttered casserole dish.

Lay the bacon slices over the top of the mixture.

Cover the casserole dish and bake in the preheated oven for 45 minutes.

Remove the cover and broil for 5-10 minutes, or until the bacon is crispy.

Let cool slightly before serving.
