This really depends on what your current weekly shop includes. You will not be purchasing takeaway's, or processed packaged goods. However you are likely to purchase more vegetables and leafy greens.
The food plan allows you to pick and choose what you would like to include in your meals, therefore, you could choose chicken instead of salmon for example, to make your meals more affordable.
We have been blessed this season with good vege growing weather, which has brought down the cost of some favourites!
The pantry staples that you may need to purchase if you dont have them already are: olive oil, himalayan salt, natural sugar free seasonings, herbs and spices.
