I always want to use mine more, but so often I find that the meals in the crock pot kind of come out the same.... mexican flavored slop, Italian flavored slop, Indian flavored slop..... that I don't end us using it as much as I would like.
There are 3 meals that I consistently use it for and have for years.
. Whole turkey breast. I do this a few times a month. Put a whole turkey breast in the CP and set to low. Add a little liquid (I usually use wine, but have used orange juice, pineapple juice, broth, water, etc), a diced onion on top, whatever spices you want (rosemary and thyme is a big one here, but I have done Italian spices, mexican spices, jerk rubs, anything) and set to go for maybe 6-8 hours. The turkey seriously falls off the bone

This chicken
https://www.food.com/recipe/crock-pot-chicken-with-black-beans-cream-cheese-89204 - awesome because you can use frozen chicken breasts.... which is good for me because I forget to thaw the day before. And you don't have to add the cream cheese at the end if you want to keep it a little lighter.
