Slice the tops of the bell peppers off and remove the seeds and membranes from the inside. Set aside.
Add the remaining ingredients to a mixing bowl and carefully mix until everything is fully combined. Taste and add more salt if needed.
Place the peppers in a 9x9 inch baking dish and divide the mixture evenly between the peppers.
Cover with foil and bake for 20 minutes, then uncover and bake for an additional 10-15 minutes or until the peppers are tender but still crisp. You don’t want them too soft.
