Install a pan on a burner, heat a small portion of oil, toss in the pieces of pepper and a tooth of garlic, pre-crushed with a knife or a garlic press, saute for about 1 minute. Then toss the mussels and squid in, previously draining off the excess oil, in which they were. Despite the fact that seafood is already marinated, it means that it is ready, it will be more tasty, if you fry them a little with peppers and garlic (1 minute). Saute the mixture, without covering it with a lid, stir constantly with a wooden spatula. If necessary, the contents of the pan can be seasoned with salt and pepper.
