Eating healthy is expensive!

Try buying frozen vegetables so you are not throwing out stuff that is out of date from your fridge every week. Frozen berries as well are a great idea and perfect for smoothies they are much cheaper than fresh berries. When I started I bought way too much fresh food for the week and half of it would go to waste as I didnt plan my meals well enough in advance and bought too much of certain foods.
Now I only buy frozen spinach, broccoli, cauliflower and berries and that brings the bill down a bit. Try planning what you are going to eat for the week before you go shopping and have a list. prep is key for good food choices.
