Yes, these stuffed peppers have bacon in them. And almost everything is better with bacon. These aren't necessarily easy, though since I'm only feeding the two of us (or three of us, when our younger son is home from college), I use my trick of cooking half the batch the day I make it and freezing the other half for another day. And even if it isn't easy, it's totally worth it.
Here's the original recipe, from AllRecipes Magazine. Go look at it, then come back and I'll tell you what I do differently. http://allrecipes.com/recipe/77194/bolognese-stuffed-bell-peppers/
Okay, you're back. First off, I found that the filling works for 4 whole medium-size bell peppers, or 8 half peppers sliced lengthwise, not 6 whole/12 half. When I'm dividing the batch, I put half the filling into 4 pepper halves, or 2 peppers, and freeze the other half of the filling in a freezer zipper bag. (When you freeze and cook another time, the rice does get a little mushy, but let's be honest. You're not eating this for the rice, you're eating it for the bacon.) I don't stuff the other peppers until the day of cooking. I like to get a combination of different color peppers; red and gold or orange are my favorites, because they're tasty and it makes a pretty and colorful presentation. Blanch the pepper halves in boiling water for about 30 - 60 seconds; this will help them cook better in the oven.
Also, the original recipe says you can use pancetta or bacon. I skip the fancy stuff and just use bacon. I figure one bacon strip per whole pepper (or four strips for the whole batch, to make filling for four peppers/8 halves). Of course, it probably wouldn't hurt anything if you throw in an extra strip :-D
On to the vegetables: I increase the minced carrots to about 1/4 c., skip the celery because gross, and also add about 1/4 cup finely diced bell peppers (green or red is my preference) and the same amount of finely diced zucchini. So along with the pepper halves that hold the whole thing, you're getting a bunch of good veggies. You could also add finely chopped spinach if you're into that sort of thing. I'm not, but if you are, that's ok. I won't judge you.
Prepared marinara sauce: I just get the Kroger store brand. It's good. You could get fancy and expensive here, but there's really no need to.
The recipe also calls for red wine, which I skip because I don't usually cook with it, and for heavy cream, which honestly seems like overkill when you're also using bacon and parmesan cheese in the filling. This recipe is rich enough without it (I can usually only eat one pepper half, or maybe one and a half, but not two) and it adds about a zillion calories. Use it if you want, but I don't.
Like I said, this is kind of a lot of work, but you can divide the recipe (or double it) and freeze half, so it's two meals for only a little more work than one. With so many vegetables, you don't need to make an extra salad or anything. I just get some bake-at-home french bread and throw it in the oven while the peppers bake, and there's dinner.
