Woman’s Day magazine publishes a monthly menu plan which is also available online. Although it’s not a gluten-free menu, many of the meals can easily be made gluten free. If you need ideas, this page has menus and corresponding shopping lists going back to January of 2008.
A couple of features I like about their menus are Meatless Monday (self explanatory) and Planned Leftovers (On Sundays, you cook extra meat which is then used in a different way on Tuesday.) While recipes are not provided for every aspect of each meal, there is a recipe or instructions for part of it. The rest is easy to figure out. For example, the menu for May 16 is mustard-glazed salmon, rice pilaf, and asparagus. A recipe for the mustard glaze is provided with instructions to spoon over salmon filets and bake. You are on your own in making the rice pilaf and asparagus.
Take a look, Woman’s Day Month of Menus might inspire you!
