what kind of things do you like? Stir frys are good because you can see how much you are making, alternatively LOADS of things are excellent cold, like tuna pasta bake, so you've got next day's lunch
If you like chicken, get two breast of chicken, marinate with salt, pepper, and crushed garlic, pour some vegetable oil/olive oil over it, and put in an ovenproof dish with potatoes cut into wedges. Cover dish with tin foil and bake for about 40 minutes on medium heat.
Accompany with boiled rice, bread or pasta.
Option 2
A mix of scotch egg sliced in two, beetroot sliced, french fries, slices of garlic bread washed down with cranberry juice - personally, I liked it!
