I used a hot Italian sausage instead of the ground beef. I ended up adding about a tsp of Italian seasoning in addition to the other herbs to add even more flavor as I didn't add the crushed red pepper--because I don't like spicy hot sauces.
This is a fabulous slow cooker recipe. I used ground beef, and had it cooking all day while we were at church and Christmas shopping. When we got home it was ready for us to eat, I just had to boil some noodles. Delicous and simple! Thanks for posting!
Absolutely delicious. This is the perfect balance of sauce to meat, and has great flavor. I followed the ingredients exactly, except I tripled the garlic (hey-we like it!) and I only had 8-ounce cans of tomato sauce, so, using 6, I had about 3 more ounces of tomato sauce than called for. I simmered on low in the Crock-Pot about 5 hours, so I didn't add the cheeses until the last 15 minutes of cooking - just enough time to melt - b/c I didn't want it to scorch while I was away. Chose for Pick A Chef '05, & sooo glad I did!!
