Woman at work wanted some easy recipes, so here's a quick go to for me. (so quick I don't have a picture of the finished product).
Roasted three poblanos on the stove - need a gas stove just rotate the pepper directly on the flame until blistered on all sides, then put in a glass bowl covered with plastic wrap to steam off the skins. rub the skin off with paper towel (don't rinse you wanted the charred taste) cut in half and de-seed.
Meanwhile put a thin layer of red sauce (basic tomato basil is good the poblanos add some spice without making it hot ) put a frozen stuffed shell inside each half pepper and put in crock pot. I then threw in some leftover meatballs I had in the freezer but that is optional(Jane likes 5 not 6 things...). Fine chopped some basil, oregano and garlic (you can use dried spice and dried minced garlic or leave off - I don't use a lot of salt so I always increase the herbs to make up for it) sprinkled over the shells, and then top with more sauce. Don't drown it - sauce won't evaporate in a slow cooker- should still see parts of the shells and meatballs.
Cook on low for at least 6, if you are working 8 or 9 won't hurt- just put more sauce on the bottom and less on top so things don't burn. 15 minutes before you want to eat sprinkle on some shredded mozzerella ( I used Sargento's pizza cheese mix this time - but any Italian/Pizza ish cheese will do) cover - and once the cheese is melted it's time to eat!
The ONLY drawback to this recipe is the cheese doesn't get brown on top. I used a crockpot liner for easy cleanup (seriously whoever invented these is a genius!!!) but if you want brown you can always skip the liner and then before serving hit it with a kitchen torch, or I guess you can torch it on the plate or use an oven proof plate and throw it in the broiler a minute before serving. I just deal with no brown. It's still good.
