As I have posted previously, one way to save time and money is to use a crockpot to cook meals.
Here is a link to a blog post with 101 crockpot recipes. The recipes cover main dishes & soups, side dishs, desserts and beverages.
Some people use crockpots in the summer so they don't heat up their kitchens. I tend to use it more in the winter months for soups and other comfort foods.
