My cooking tends to go in cycles. I get a dish or two and will cook it or a variation of it for weeks. And then I'd get inspired to something else, and that becomes my go-to meal. My current go-to is baked fish (namely Salmon, because I don't love other fish like I love salmon).
I started with a recipe from Nom Nom Paleo called Fish en Papillote. It's been the perfect meal-for-one after I finally get home from work/gym/class. I don't follow the recipe that closely, just turn my oven on to about 220C and bake for about 10 mins.
My crazy schedule makes it too easy to fall into lazy, unhealthy meals or expensive eating out. This eases some of that - not that salmon is really 'cheap'.
