Ingredients
150 gram Wholemeal pasta shells
1 number Large tin of tuna in springwater
1 number Sweetcorn-400 gram tin
450 millilitre Nonfat milk
1 tbsp Wholemeal flour
1/2 tbsp Reduced fat butter
200 gram Lowfat mature cheese
1 tsp Grainy mustard
150 gram Frozen petit pois
1 gram Salt and pepper
Directions
- Cooked vegetables to serve on the side – such as green beans, cauliflower or broccoli
- Cook the pasta in boiling water for approximately 15 minutes
- Once the pasta is fully cooked, place into an oven dish with the tuna, peas and the sweetcorn.
- Heat the butter in a large saucepan then add in the flour and stir well, then cook for a few minutes
- Next add a small amount of milk and stir really well. The mixture in the pan should swell and start to absorb the milk. Continue to add the milk a bit by bit, stirring so that the mixture doesn’t go lumpy, until all of the milk is added. Lightly cook for a few minutes until it thickens, then add three-quarters of the cheese and all of the mustard. Season with salt and pepper.
- Next pour the sauce over all of the ingredients in the oven dish. Top with the remaining cheese and put into an 180C oven for 15-20 minutes until bubbling.
- For some extra flavour add a garlic clove to the white sauce. Serve with a big plate of mixed vegetables.
