Cook the tender wheat al dente according to the instructions on the packet. Wash the peppers, cut off the `lids` horizontally and store them, remove the partitions and kernels from the pods.
For the tomato sauce, fry the finely diced onions and garlic in a large saucepan in olive oil, pour on the tomatoes, season the sauce with salt and pepper and simmer over a low heat.
Cut the sheep`s cheese into small cubes and mix with the tender wheat along with the chopped parsley and a little paprika. Fill the peppers with the mixture, put on the `lids` and place the peppers in the sauce. Cover and simmer for about 30 minutes until the peppers are done, but still a bit firm to the bite, if you like them softer, you should expect 10 minutes more.
