Brown ground beef or ground turkey and drain well. For easy clean-up either spray your crockpot or use a crockpot liner. Place package of frozen ravioli into crockpot. In a mixing bowl, mix pasta sauce, browned meat and spices. Mix well and pour over ravioli. Top with 1 1/2 cup mozzarella cheese. Cook on low about 4 hours. Depending on how your crockpot cooks, it may be done sooner. [Dana said hers was done in 3 hours, so be sure and check!] (Midway of cooking time, stir.) Top with remainder of mozzarella and let cheese melt.
