On to the paella, which requires lots of steps, so if you want something fast and easy, well you can go get yourself an Uncle Ben's rice bowl or some lame shit like that.
In a big stainless steel pan (or paella pan if you happen to have on lying around...) sauté half of a finely diced red onion, half of a green and red pepper. Add some diced chicken or rabbit. While that cooks, bring 50 mL of water to boil for the mussels (the cooking liquid is added later to the dish). Toss in the mussels, cook till they are all opened.
Back to the big pan: add a diced tomato, two cloves minced garlic, some chopped parsley, fresh thyme, paprika, salt and pepper.
