I loves me some onion and garlic. I can cook, but not well. I'll usually fry some garlic and onion, and think to myself, "What can I actually make using garlic and onion?" That's when I throw together some other chopped veggies (whatever I have in hand), fry it, and add some kind of sauce. Sometimes I'll just mix some sauces together and make something entirely unusual. I never have plans for my garlic and onion. I just know it's going to be in whatever I cook. Anyway, I don't know why, but that combination of things happens to go together like.......like.....chicken + avocado, Romeo + Juliet, Mad Jew + brooms, peanut butter + jelly, and of course the grilled cheese sandwich, which is just cheese + tomatoes in bread, and grilled in a sandwich press (aka: sandwich "maker"). Is there any reason why some things just happen to go together better than others?
