Tortelloni bake

This was inspired by Easy Cheesy Vegetarian's recent post, and also by my original macaroni cheese recipe.

1 packet fresh tortelloni (your choice of filling)

2 small onions

2-3 cloves garlic

1 tbs sunflower oil or similar

1 tin tomatoes

1 tbs plain flour 

Seasoning: salt, pepper, dry mustard powder, herbs or spices as liked

Handful grated Cheddar (didn't measure, probably around 50g)

1 tin sweetcorn

1/2 packet halloumi cheese

Chop your onions and garlic and fry gently in the oil in an oven-proof dish (cast iron is ideal).  While this is happening, boil your tortelloni for 3 minutes.  Drain into a sieve.

Meanwhile, put the tinned tomatoes, flour, seasonings and the liquid from the tin of sweetcorn (if there is any - some brands are more-or-less vacuum-packed) and blend until smooth.  

When the tortelloni have finished cooking, put the blended tomato mixture on top of the onions, raise the heat and stir vigorously until it comes to the boil and thickens.  At which point, turn off the heat and add the grated cheese and the sweetcorn,

stir, and then add the tortelloni and stir in, flattening off the top. 

Now cover the top with sliced halloumi,

and bake at mark 6 for about 30 minutes.
