Oh there are so many delicious options!!!
*Sandwiches like PB & J, or try fake meats, as well as tempeh with different marinades, or one with just tons of veggies
*Oatmeal- I like mine either cooked with some dried fruit and a shot of agave nectar (don't use the powdery instant, go for the five grain instant at Whole Foods, totally different and way better) or raw with fruit and nuts, plus some almond milk
*Pasta! Experiment with different sauces, and try out the whole wheat kind- so good. Also, I like to throw in veggies with the sauce that I'm heating up in the saucepan. It's an easy way to get more veggies in.
*Sloppy Joe's- Get the veggie beef crumbles and mix them together in a skillet with ketchup, mustard, relish, whatever you like in sloppy joes.
A big hint that I have is to make huge batches once a week and eat off the leftovers. A really, really good cookbook is
Vegan With A Vengeance by Isa Chandra Moskowitz, even if you aren't planning on becoming vegan. It's full of really easy recipes that make huge portions. Also, you might want to check out her website
www.theppk.com. These two things are my vegan bible.
I wouldn't worry about giving up seafood (if you want it, I have a really good recipe for tofu fishsticks that are divine), and if it's an issue of being a bother for your parents, just remember that it's your body, therefore you get to choose what goes into it. I haven't eaten meat since eighth grade and I'm glad I chose that option every day. Good luck with your journey and please feel free to ask any questions (you can PM if you need recipes, I have plenty).
