One of my favourites is to prepare a variety of healthy foods and roll them up in a tortilla. I usually prepare some extra firm tofu, avocado, cilantro, hemp seeds, celery, and wrap them in a corn tortilla.
Try cutting down on or eliminating meat and dairy from your diet, there's sufficient evidence that proves meat and dairy are not necessities in the optimal diet and are actually the cause of many health issues. meat has a strong correlation with heart disease, stroke, and high blood pressure while dairy has been linked to osteoporosis (ironic isn't it?) and many cancers.
I went vegan 6 months ago and have been pleasantly surprised at the myriad of health benefits I have experienced; much more energy throughout the day, a lot happier and motivated, anxiety has been eliminated, cuts and burns heal much quicker, much clearer/healthier skin (although i've always been pretty lucky when it comes to acne), I can concentrate much better and for longer periods of time, and the list goes on...
I eat a lot of hemp seeds, nuts, lentils, and hummus to reach my daily protein goals. I eat a lot of veggies and a daily multivitamin to reach my daily calcium needs.
I expect this post will likely be bombarded by -frags since meat and dairy is the status quo but I recommend you do your own research, American meat and dairy industries have money in so many studies, researchers, health institutions, policies etc and they use the same tactics as the tobacco industry did decades ago to confuse the public about the real truth.
