How to Make It
Preheat oven to 400°.
Cut peppers in half from the stem down and remove seeds. Place in a large microwave safe bowl with 1/3 cup of water, cover with plastic wrap and microwave on HIGH for 4 ½ minutes or until peppers slightly soften. Uncover and set aside.
Heat 1 Tbsp. olive oil in a large skillet over medium-high heat. Add ground beef and cook, breaking up pieces for 6 minutes or until browned. Drain. Return meat to the pan. Add onions, zucchini, garlic, oregano, salt and pepper and cook, stirring occasionally until vegetables are tender, about 6 minutes. Remove from heat. Stir in tomatoes, olives, feta, couscous, and 2 Tbsp. chopped mint. Spoon evenly into peppers (about 3/4 cup each) placed cut side up in a 9 x 13-inch baking dish. Bake for 15 minutes or until peppers are tender. Garnish with remaining mint.
