This is a super filling, power lunch, which should help me run 10k tonight (that’s the plan anyway!).

1) boil a pot of wholemeal pasta.

2) drain pasta and return to pan. Stir in a spoonful of butter and a handful of grated cheddar.

3) add a tin of tuna steak and a tin of sweetcorn. Stir on the heat so the cheese and butter melts.

4) stir altogether and add a grind of black pepper.

Pop in tuppaware, grate some cheese on the top, and take to work. I have mine cold but you could warm it up.
