it does cost more for organic
But, I know that we make a healthy lunch for my mother out of inexpensive veggies and a smidge of chicken broth. I dice up zucchini, green cabbage, and what ever left over chicken we have. I add salt, salt substitute (potassium) and little pepper. It all goes in a plastic box. Microwaved. And its soup. Very healthy. She also has one orange. Breakfast is a bit of avocado, a hardboiled egg, whole wheat bread and 1 ounce cream cheese.
I do a good portion of the grocery shopping and for a week its one cabbage, 6 zucchini, 1 box of organic lo-sodium chicken broth, foster farms chicken breasts, 1 loaf of bread, 1 brick of cream cheese, and 6 oranges. The veggies are about 3 dollars. The broth is 3.5 dollars. Over all I don't think its the veggies that up the cost. Dinner is more expensive cause both of us eat. I cook vegetables and some protein. Usually chicken or beef. She likes cauliflower best. And its easy.
