Tough call. I can narrow it down to, let me see, four possibilities:
1.) Grilled cod, potatoes, peas, and lashings of cheese and wholegrain mustard sauce.
2.) Mashed potatoes, chopped mackerel, peas, all mixed up together with lashings of salad cream.
3.) Roast chicken, roast spuds (Aunt Bessie's or Tesco's own are fine), peas, wholegrain mustard, and lashings of gracvy.
4.) And before you spot a theme developing, cheese and tomato pizza.
I think I'd probably get bored of (4), so it'd have to be one of the first three, but I can't narrow it down right now.
