Circle of Friends Cookbook - 25 Burger Recipes - Gooseberry Patch Another free Kindle cookbook from Gooseberry Patch. This may be my favorite of the bunch if only because I love all things burgers. The recipes are simple but inventive. I tried the Fajita Turkey Burger last night and my wife liked it even though she usually runs from turkey burgers. I thought it was the best turkey burger I ever ate. Beef burgesr get the nod too but you will also find burgers with salmon, chicken, tuna, even veggies. Worth paying for if it wasn't free.
