I have recently started using meat from Muscle Foods.
They specifically sell lean meat in vaccum sealed packs and deliver straight to your door. They also stock some great Nut Butters!
In my order I got Lean Mince, Chicken Breast, Lean Bacon, Lean sausages, Protein Pizza, Sweet Potato Wedges and 2 Nut Butters.
Not only is it delivered to your door, it is also very good value for money compared to supermarket prices.
If you want to place an order or check out their website you can find them here.
