Spicy Spinach and Artichoke Dip

Melt butter in a large saucepan or skillet over medium heat. Add onion and cook until soft, about 5 minutes. Stir in spinach, artichokes, cream cheese, sour cream, 3/4 cup of the Monterey Jack cheese, 3/4 cup of the Parmesan cheese, TABASCO^® Sauce and salt. Stir until well blended and heated through.

Pour mixture into a 1 1/2-quart casserole dish and top with remaining 1/4 cup Monterey Jack and 1/4 cup Parmesan cheese. Bake in a 350°F oven until cheese starts to brown, about 10 minutes. Serve with pita bread and garnish with tomatoes.
