In an oven-ready 9-inch pan, mix the spinach, garlic, onion, sour cream, cream cheese, 1 cup of Armstrong Mmmm...Bacon shredded cheese, Parmesan cheese, Worcestershire sauce, salt and black pepper, with hot sauce (optional). Mix well.
Sprinkle the remaining Armstrong cheese on top.
Cook in the oven for 20 to 22 minutes, or until the cheese is melted and bubbly. Broil for an additional 5 minutes, or until the cheese turns golden.
Garnish with crumbled cooked bacon, and serve hot with toasted baguette, vegetables, crackers or chips.
