Pour 300 ml of lightly salted boiling water over the bulgur and let it swell for 15-20 minutes. Pour it into a bowl and let it cool down a little.
Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). Peel and finely dice onion and garlic. Knead with minced meat and mustard. Season with about 1/4 tsp salt and pepper. Form into 6 rolls and put them lengthwise on skewers.
Place skewers in a large casserole dish and spread with half of the teriyaki sauce. Bake in a hot oven for about 15 minutes. Turn over and spread with the rest of the sauce.
Clean, wash and finely dice the peppers. Wash the coriander, shake dry and chop coarsely. Mix bulgur, paprika, coriander and lemon juice. Season to taste with salt and pepper. Serve the bulgur with the skewers.
