I much prefer cooking for friends and family, but my job has taken me away from home and I spend a fair amount of time cooking for myself. I have learned to LOVE my foodsaver and my freezer. The toaster oven is a lifesaver as well, because I live in FL. HATE to turn on the whole oven for a little chicken breast!
One of my favorite things is pizza. I make my own crust, which makes enough for 4-6 individual pizzas. I will make one pizza, then I will shape the remaining dough into individual pies and stick them in the freezer. When I come home last minute, all I have to do is take a frozen crust out of the freezer, spread some sauce and (usually also frozen!) cheese on it and pop it in the oven! Add whatever toppings are available as necessary! Awesome, fast, and CHEAP!
One of my friends was over the other day and laughed at my freezer list, but I don't care. He goes out to eat all the time. He acts like he's putting me out when he comes over and I want to use up some of my food instead of going out and spending $20 on a mediocre meal (I'd way rather cook than spend money I don't have eating out!). I'm proud of the fact that I make my own hot pockets (also with my homemade pizza dough) and uncrustables for last minute lunches and have an assortment of dinners stashed in my freezer!
