and you cannot commit to a completely vegan diet (YET!), then check out No Meat, No Dairy, No Problem
Each week, pick a day to eat a completely plant-based diet. It is not hard to do. For breakfast, replace dairy milk with soy, almond, hemp, coconut or rice milk in your coffee and cereal. Or try coconut milk yogurt or soy yogurt with fresh fruit. It is easy to make pancakes by replacing cow's milk with nondairy milk and butter with soy-based margarine.
For lunch, you can rely on peanut butter and jelly sammiches or a fresh tomato soup with some french bread to dip in. Salads are easy to veganize. If you live in an area that offers Daiya (Raleys, Safeway) in the "natural" food section, you can make a mean grilled cheese sammich too!
Dinner can be bean burritos or fajitas or pesto pasta or veganized lasagna, if you're fancy.
There are far more vegan food items available than non-vegan ones. Far more. Replace your favorite dishes slowly. Your taste buds will adjust and you will probably find yourself more open to new tastes and flavors.
