Cut the chicken into strips. Divide the chard lengthways into 3-4 pieces, then cut into bite-sized pieces. Peel and dice the onion and garlic. Clean the peppers and also dice them.
Boil the pasta and chard in plenty of salted water until al dente, pour off and keep warm. Heat the oil in a pan and fry the chicken strips, onion and garlic cubes vigorously. Season with salt, pepper and paprika. Then add the pepper cubes. Mix the cornstarch with the chicken stock and stir in the cream. Let everything simmer for about 5 minutes.
Fold in the pasta and chard and simmer for another 2 minutes. Season to taste again if necessary.
