I have a cast iron skillet that I roasted all the veggies on prior to give it that tasty brown crust, especially on the tomatillos. That deepened the flavor profile so much more than simply throwing them in the cooker and wishing them luck I believe. I did add a little ground turkey but I don't think it needed it -he won't eat anything without meat. I also did the quick soak method on my beans (bring to boil in pot, boil 2-3 minutes, sit for hour and rinse) and after being in the crock pot for 8 hours they came out perfectly cooked. I highly recommend getting on the dried bean train, you will save so much money!! Also I wasn't sure what kind of mushrooms to use (recipe doesn't specify) so I used sliced baby portabellas on sale and the "fancy" blend of mushrooms in a package. Those were expensive but I feel like they deepened the flavor.
Overall this was a rich dish with a hearty full feeling after. I can see how some people may not like it if they didn't add some browning to veggies, they may just melt and be boring. Try it again!
