Because flat-iron steaks are well marbled, there's no need to add oil to the skillet. When cooked up to medium, they remain tender and juicy. You sear the steaks in step 1 and use the skillet for a quick wine sauce in step 2. Our stir-together mustard sauce is another delicious accompaniment.
Instead of ground beef, fill flour tortillas with tender steak and a quick cabbage slaw -- all ready in 20 minutes. Marinated cabbage salad makes a tangy partner for meaty tacos. A little lime juice is enough to soften the cabbage.
