@mcgugan's pinto bean recipe

	Cook the pinto beans in a pressure cooker with 3 parts water to 1 part beans, and some salt.

	While that is cooking dice an onion and 3 stalks of cellery, add a few cloves of garlic crushed with a knife. Fry lightly and stir for around 20 minutes. Add sliced sausage and fry for another 10 minutes.

	When the beans are ready take a couple of scoops and add them to the onion mixture. Mash the beans so they are completely broken down (this will thicken the sauce). Add paprika, chipotle, tomatoe puree and black bepper, then combine with the beans.

	Simmer for another 10 minutes or so until the sauce thickens. Add some vinegar and chopped parsely near the end.
