As I always suggest - go to the grocery store and just wander. You will notice foods you have never seen before.
Most grocery stores carry items such as dried onions (spice aisle), sun-dried tomatoes air dried (produce) and many will carry even freeze-dried veggies in the snack/chip aisle.

As Grannyhiker pointed out my website - the concept when I started doing all this was FBC (Freezer Bag Cooking) which was simple, easy to make meals requiring just you, bags and a visit or two the store. The recipes on my website do range from simple to gourmet, my book though is all about grocery store meals.

What do you like? If so I can point you in the direction of various recipes you might like!
