Help!

I'd say one of the easiest things is chili. Just throw in onions, carrots, peppers, tomatoes, and whatever other vegetables you happen to have on hand. You can buy chicken or beef depending on what kind of chili you like. Diced tomatoes, some beans... if you have a crockpot you can simmer it in there all day, or you can easily find a quick chili recipe to make on the stove. It can last a long time, too!

Here an easy soup.

My advice would be to start with what you like to eat and find ways to make it healthier. Most of my eating plan has involved substituting starches like rice, pasta and bread for something better, mostly vegetables. Rice has been switched for cauliflower, so has mashed potatoes, pasta has been replaced with zucchini, I eat flax seed flatbread instead of white bread etc. There's an option for everything if you Google it!
