Yes, the crockpot makes it easy to cook meals while at work and stuffed peppers is one of them. Stuff them how you like them - for example with beef, rice, chopped onions, tomato sauce, Worcestershire sauce, and spices such as garlic powder Italian seasoning, crushed red pepper, salt, and pepper. When you have them how you like them, you can put the in a crockpot (and you can stack them if you wish) for 6-7 hours on low or 3-4 hours on high. Yum!
