For some it is impossible not to think about Sunday meals at grandma’s house when they try a good paella, a stew or some casserole noodles. In this case, we propose a very easy recipe to prepare, which will not take you more than 30 minutes, and which mixes the intensity of the red pepper with the sea flavor provided by the mussels and crayfish. A perfect preparation both for those family meals and to give yourself a bath of nostalgia.
