Hi, I just did one last night for dinner, I used diced pork (leg) onion, leek, carrot, swede, parsnip, button mushroom and chestnut mushrooms (all chopped to a similar size) then I used a packet of Peppered beef caserole mix (from Morrisons) it works great with any meat Beef,Pork and Chicken, it is a lovely herby spicy mix makes the 'gravy' of the caserole very tasty, I served this with homemade soda bread (easy recipe, 250g Plain flour, 1 tsp baking soda, 1 tsp salt, 200mls buttermilk, mix all together turn onto a floured surface and knead for 1 min, don't worry it is a very soft sticky mixture when turned out, form a round then cut a cross in the top, bake for 40 mins 200c)
Or sometimes I serve it with baby potoatoes its up to you, but I think you will enjoy this recipe and use it again and again ( I do, its a hit in our house) Good luck
