Saute the sausage with your diced onions. Then add your tomatoes and chicken broth. Once the sausage is cooked, slice it into quarter inch pieces. Add your sausage and carnitas into a saucepan and saute together.
Once you have mixed the two meats together, take them off the burner. Now cut your poblano peppers, wear gloves and de-seed the peppers. Pre-heat your oven to 350F.
Add a third of your cheese to each pepper, then add your meat filling, and finally cover with some more cheese.
Place the peppers in the oven, bake for 20 minutes and enjoy!
