Crockpot Spicy Spaghetti Sauce

This is my friend Janet's spaghetti sauce and it is so tasty. This recipe makes enough sauce for 2 spaghetti dinners or 2, 9x13 pans (4, 8x8 pans) of  Janet's Mostocioli Pasta Bake (I've listed this recipe separately). So you can have it with spaghetti one night and then freeze half and make Mostocioli Pasta Bake another night. I love great double duty recipes! Thanks Janet!
