I created this rustic dish (with much inspiration from a BHG recipe) to use some homemade chorizo sausage. I quite enjoyed the results...hope you do to!
In a large skillet cook chorizo over medium heat about 5-7 minutes or until cooked through. Use a wooden spoon to crumble up the meat as it cooks. Remove from heat and drain off any rendered fat.
In the same skillet, mix spinach, beans, onion, milk, 1/4 cup of the cheese, lemon juice, nutmeg, and pepper with the cooked chorizo.
Transfer mixture to a greased 2-quart baking dish.
In a small mixing bowl combine bread crumbs, remaining 1/4 cup of cheese, garlic, and melted butter; sprinkle over casserole mixture.
Bake, uncovered, in a 375° F oven for 35 minutes or until heated through.
