One of my favorite things to have on hand are Wild Alaskan Salmon Burgers from Costco. A bag of 12 costs about $13 and they cook in 5-8 minutes. They're super versatile; I eat them on buns, salads, with pasta, with eggs.
For a lazy, quick lunch today I boiled some pasta, added frozen edamame 5 minutes before it was done, and put a salmon burger in a skillet. When the pasta and edamame were cooked, I added them to the burger, flaked it, added a little olive oil, lime juice, dill, red pepper, salt/pepper.
delicious.
