1. Cook sweetpotatoes for 20 minutes. Meanwhile mix mustard, orange juice and ½ teaspoon salt. Stir in olive oil bit by bit. Wash the thyme, shake dry and pluck leaves from stems.
2. Wash and dry bell peppers. Quarter them and cut out the core. Wash salad and spin dry. Drain the sweetpotatoes, leave to cool and peel. Halve lengthwise and cut into slices.
3. Season steaks with salt and pepper. Coat the grill with oil. Grill steaks on the hot grill from each side for 3 – 4 minutes. Wrap in aluminium foil and let rest for 10 minutes. Meanwhile grill potatoes and peppers while turning. Mix the potatoes and vegetables with the vinaigrette. Cut the steaks into fine strips and add to the potatoes together with the salad. Mix everything well and serve.
