Arrange the peppers in a greased baking dish, cavity side facing up.
Fill each bell pepper halves with the ground turkey-green beans mix.
Bake uncovered for about 30 minutes, or until the peppers are cooked and soft.
Remove from the oven and garnish with parmesan and parsley.
Notes
For the bell peppers, keep in mind that the sweetest ones are the red bell peppers and the greens are the least sweet, so I try to use red, orange, or yellow bell peppers.
You can put the onion, carrots, and garlic into a food processor to mince them finely so they fit into the bell peppers.
Make sure to trim the green beans before using, as the ends can be tough and stringy.
To store: Place stuffed pepper leftovers in the fridge in an airtight container for up to 4 days.
To reheat: You can reheat the stuffed bell peppers in the microwave or oven.
To freeze: Tightly wrap up each of the stuffed peppers and freeze them for up to 3 months.
