Grain-stuffed marrow

½ large marrow
1 onion
1 clove garlic
½ punnet mushrooms (about 8)
1 tub or tin chopped tomatoes with chilli
1 packet microwaveable mixed grains (I used Middle Eastern)

Peel and chop the onion; peel and crush the garlic.  Add both of these to a saucepan with a little cooking oil, and allow to cook for a few minutes.  While this is happening, cut your marrow into 4 equal slices, then peel each slice and remove the seeds.  Place the rings thus obtained on a baking dish.

Now chop the mushrooms (you can peel them if you wish, but unless they are beginning to be old, life's too short) and add them to the onion mixture, and allow to cook until they are just rendering their juice.  Stir in the tomatoes and the grains, until the grains are separated and the whole lot is heated through.

  Now pile into the mushroom rings, and bake in a moderately hot oven for about 45 minutes.
