Dinner for one is not much fun. :)

dear fellow bloggers, I've learned many things from this blog, but mainly I've learned that cooking is absolutely exhausting. It's not even the actual cooking that I find impossible, it's the planning ahead. When you're little and tailing your parents around pointing at things like dunkaroos and popcorn you don't realize that a lot more planning goes into grocery shopping than just saying "oh, that looks good." You have to think to yourself, will eating this for dinner tonight contribute to my vitamin B12 deficiency (is this meat or something I don't feel sad eating), should I get orange juice or cranberry juice (do I have a cold or do I have... something else), yes this dessert may include 3/4 of my daily allowance of calories but it's really yummy and OH HEY IT HAS B12 IN IT LET'S BUY IT!!! Even more challenging is judging portions. For instance, last night I had no time to cook dinner so I bought myself Safeway's roasted chicken and soup. Now I am left with 7/8ths of a roasted chicken in my fridge that expires tomorrow. I will be having chicken for breakfast, lunch, dinner, and dessert. To accompany my meals of chicken I'll be drinking a litre of milk that goes bad today, yogurt that goes bad, um, three days ago, my couscous from the previous week that I don't have the heart to eat or throw out, and a moldy loaf of bread. These are mere examples of the things I have bought with great care, only to realize that really, I only need to buy about one vegetable a day to ensure nothing gets thrown out. You guys should see my freezer. It's filled with all the things I've made, tasted, then decided I didn't want but would save for later. This includes vegetarian chilli that i was too scared to eat after 3 days because I didn't want to get food poisoning and die but I also didn't want to throw it out and waste perfectly good chilli (I figure that with time I'll be less afraid to eat it), and beet salad which is in there for the same reason (though I think beets only expire after 18 years). I guess what I'm wondering is what's the best way to portion food for one? It'd be really helpful if my boyfriend could just help me eat things once in a while, but since his pallet is only familiar with stir fry, pasta, and chinese food I know this will take some time.
