Ocado British Mini Chicken Breast Fillets. Fresh class A. Skinless and Boneless. Versatile and convenient mini chicken breast fillets are a perfect starting point for any meal. Stir fry them with noodles, roast and stuff into fajitas or roast them and toss into a Caesar salad. Chef's Tip: "For perfectly tender, flavourful chicken; marinate for as long as possible. 1-2 hours is great but overnight will really infuse the flavours" Our Ocado chickens live in barns that have natural daylight with bales and perches so that they can express their natural behaviour. There may be a slight odour on opening, which will quickly disappear. This is normal and does not affect the quality or flavour of the chicken.
