This cookbook is a collection of food I mainly ate in my younger years (the 1970s and 80s). I have made the recipes to reflect that I was a vegetarian. You can easily replace beans, lentils, etc. with the protein of your choice. Or add to the existing recipe. The recipes are cheap, healthy, storable, and easy to make, with easy-to-get ingredients. Beans and lentils are good alternative sources of protein. They are easier to store than meat, healthier than meat, and much cheaper. Most of them can be eaten as leftovers for a few days and as school lunches the next day. Many of the recipes would help balance the junk food given to children on their birthdays. My kids loved spinach pie and lasagna, etc. and i hope your kids do too. These recipes are suitable for any age.
