Clean and wash the zucchini, dab dry, halve lengthwise and cut into pieces. Clean, halve, seed, wash and pat dry the peppers. Cut the bell peppers into bite-sized pieces, except for one half for garnishing.
Heat the oil in a pan. Add minced meat and fry until crumbly. Add onion, garlic, zucchini and paprika and fry for about 10 minutes. Stir in tomato paste. Season with salt and pepper. Deglaze with tomatoes.
Bring to the boil and simmer for 2-3 minutes. Meanwhile wash thyme and shake dry. Set aside the leaves, except for a few for garnishing. Arrange amaranth and minced vegetable pan together.
