Spicy Creamed Spinach
Cook spinach according to directions on package. Drain and reserve liquid. Melt butter in a saucepan over low heat. Add flour, stirring until blended and smooth, but not brown. Add onion and cook until soft but not brown. Add evaporated milk and reserved spinach liquid slowly, stirring constantly to avoid lumps. Cook until smooth and thick; continue stirring. Add the cheese, Worcestershire, black pepper, celery salt, garlic salt, red pepper, and salt, to taste. Stir until melted. Combine with cooked spinach.
Note: I found this version kind of salty, and would put a little less then add more as needed.
