Leftover Salmon? Avocado? Bread?

Avo-toast with extra protein. Salmon is great cold, so it's worth making more than you can eat in one sitting-- as long as you don't over cook it. Just-done-enough salmon tastes much better (I think), and will taste better the next day if you decide to re-heat it. 

Lots of freshly ground black pepper, a pinch of salt, and a squeeze of lemon.
