1 In a large shallow pan, arrange the blade steaks in one layer and add the bell peppers.
2 In a blender, blend the orange zest, juice, oil, garlic, soy sauce, red pepper flakes, vinegar, and the salt until the marinade is smooth; pour over the steaks and the peppers, coating them thoroughly and letting the mixture marinate. Cover and chill overnight.
3 On an oiled rack 5-6 inches over the coals, grill the steaks and the peppers for about 8 minutes on each side for medium-rare; discard the marinade in the pan.
4 Transfer the steaks to a platter and serve.
