I'm trying my second recipe today with the crockpot. It's a TURKEY CHILI. Easy to make. The base ingredients cost less than $8 (beans, ground turkey, tomato soup), although I did have to buy some spices which can be used in future meals.
It completely filled my 4 quart cooker, so I'm looking at eating chili for the rest of the week.
The hardest part is going to be sitting right behind it all day as it cooks. The smell is fantastic.
