So i thought, ok, whats simple and quick. answer: a tomato sauce. Ran to the pantry, and found a red onion, 1 tin of tuna, 4 tins of herring, and a big tin of diced tomato. Perfect.
Right away i fried up the onion, added some olive oil, salt, pepper, and paprika (i'm sure i didnt spell that right). After it was nice and soft, in went the tomatos, a bay leaf, oregano parsley and basil, a cup of water and a quick splash of our fancy balsamic viniger. I let it reduce down until it was about as water as the pre-water mixture appeared, then added the tuna, one tin of herring, and the last bit of smoked salmon i had in the fridge. 5 minutes later, all was good, and i started to divide it into 5 portions.
Total time from realizing i had to make something to having a fully cooked and somewhat nutritionaly balanced meal: 21 minutes.
Not to bad for grabbing what i had laying around.
