Mathews Butcher Grass Fed Beef Eye-Fillet Steak | Approx. 250gGrass Fed Beef Eye Fillet Steak (Approx. 250g Per Piece) The eye fillet is a long, tapering muscle that doesn't do much work which means it doesn't have the flavour profile of a hard working cut like skirt or chuck but also why it's so tender, delicate and lean. All fresh Mathews meat products are best cooked within 2 3 days.
