Ocean Pie

What is it?

Mixed seafood sits in a creamy sauce under a layer of mashed potato. Expect pieces of fish and shellfish folded into the filling, with the mash forming the top rather than a separate side. It comes as a frozen pie for oven heating, which means the sauce thickens as it cooks and the potato lid browns at the edges. In M&S’s frozen meals range, this leans more toward a pie-and-mash format than a pastry pie, so there’s no crust to cut through. The focus is on the sauce, the seafood mix, and the soft potato topping.
