3. Vegetables: tomatoes, cucumbers, and fresh mixed greens
You are absolutely right if you think that it is impossible to have a healthy diet if it does not contain vegetables. There are hundreds of various veggies, and some of them might be relatively expensive. Nevertheless, there are very cheap veggies that you can eat every day! First what you should remember is: never buy vegetables in large quantities. Pick 3-4 types only. If you buy a lot of veggies at a time, you will probably throw some of them away since you cannot keep them fresh for too long. You can opt for mixed greens instead of whole because they are sold discounted, especially when they have next to no shelf life.
