im a vegetarian and im trying to go vegan. if i go to the store what kind of foods can i buy. i mean like ik soy yogurt and ice cream but.... isk what els ik fruit and veggies obviously. ik a lot of cereals arent vegan so do they have that? sorry i probably sound really stupid but i live with 3 meat eaters and the only vegan thing i have in my house id almond milke and non dairy butter... arent vegans suppose to eat organic stuff?? cause i have like bananas and pears and stuff but non organic.. somone tutor me on this and my parent are probably gonna hate me going vegan why is it a bad thing to them.
