New Diet

Helloooo, I'm going to be hitting a health food store and I would like to try things such as Soy Milk/Almond Mlk but what healthy snacks/foods can I get so I have something to eat while the rest of my family eats Burger King? Lol. I've been drinking a lot more water lately, but other than that.. my diet hasn't changed too drastically. I'm not much of a cook so homemade dinners are out :/ Thanks!!
