Get the campfire going and light the coal briquettes. You will need 14 briquettes.
Cut the tops off of the bell peppers and clean out the inside. It’s important to cut the tops enough so that they will fit inside your dutch oven with the lid closed.
Brown the beef.
Chop the mushrooms.
Mix together the beef, mushrooms, lime juice, and salsa in a bowl. Make sure the salsa coats everything.
Spoon the mixture into your peppers and place into the dutch oven.
Place 7 coal briquettes on the bottom and seven on the top of the dutch oven, and bake for 30 minutes.
