kitchen improv: white bean linguini

Kitchen Improv is where I read a recipe, in this case, this one, am missing many of the ingredients, go into the kitchen, and try to cook up something like it anyway, reconstructing the gist of what I read before.
So, I may have mentioned once upon a time that I had a lot of frozen white beans? Well, I still have some of them, and  I'm about to move, so it is time to Clean Up Frozen Things. Here is what I did.

1. Cook linguine. That part should be easy.
2. Fry up some onions and garlic in generous olive oil. I used three fat cloves of garlic and most of a small onion ("most" because part of it looked funny), but I would recommend using more, because garlic is awesome.
3. Add to this about a cup, heaping, of white beans, and a cup of chicken stock. Also salt, pepper, and a large portion of oregano.
4. Cook this down to sauce-like consistency, and mash up the beans as you go. If you are impatient and have too much liquid, which I did, you can add tomato paste--which I had, and the original recipe had sun dried tomatoes in it so I thought something tomatoey would be good. The exciting part about this is that I do not have a can opener, although I have canned goods, because it got rusty or something and my roommate threw it away. In this situation, you can still open cans by poking a hole in them with the back end of a hammer, and then cutting a hole with a knife. Tomato paste cans are a poor choice, because they are small and thus more structurally intact, and also their contents don't pour, so then you have to scoop it out spoonful by spoonful while attempting not to cut yourself on the ragged metal edges of the little hole you made. Guys, I don't recommend this course of action. Keep your rusty can openers. Anyway, add maybe half the tomato paste.
5. Serve! Add lots o' cheese.

This produces about two portions of sauce, I'd say. It needed to be slightly more vigourous in flavour, but I am not sure what it needed, so I'll go with garlic. Maybe salt, too. It was pretty delicious, but it needs beta-testing. I wouldn't make it for a dinner party, but maybe for people who were hungry and not judgmental would like it.
