4) Make a meal plan. Before you jump in head first, think through what you will eat. It is a good idea at this point to purchase a vegetarian cookbook to guide your efforts. Do you remember your one-day experiment? You probably did not plan well on this day, and you probably encountered some problems, such as finding something to eat at a restaurant or discovering that you did not have the ingredients at home to make a quality vegetarian meal. The best way to solve this problem is to plan well. For at least the first few months, you will want to experiment with various meals. Use your cookbook often. Make a weekly grocery list based on the recipes. You will be more likely to stick with the vegetarian lifestyle if you are prepared.
