This is what we’d all be making if we had a lazy few hours and the need to get ahead in life prep – a wholesome slice that will find a happy home in a kid’s lunch box, a brunch table or cut into dinky squares as a canapé. We supply the uncooked mix of roast, sliced zucchini, pancetta, free-range eggs, tasty cheese and enough flour to bind – you just whack it in the oven straight from frozen.
