Since moving in with my friend, having a household of just us two dudes has forced us to learn to cook.
One thing I've made a couple times that is good is linguica and rice. You cut up a pound of linguica, brown it with I think like a quarter cup of butter, and I usually chop up some onion and throw that in with it too. Once the linguica is browned you put in two cups of rice, 4 cups of water, and some salt. Let it cook until the water is gone. I also usually cook it with crushed red pepper too since if food doesn't make my mouth hurt when I eat it why even bother.
