This recipe is SO GOOD and SO EASY! I have made it twice and only thing I changed about the recipe was omitting the mushrooms because I don't care for them. I don't really see the need to cook this for a full 7-8 hours in the slow cooker. I cooked it for about 5.5-6 hours and it was just fine. After adding in the tortellini, I sprinkled a pretty generous amount of cheddar and mozzarella cheese covering the top of the mixture and by the time the tortellini was cooked, the cheese was melted just the right amount. No complaints here!
