Nicoise salad - lettuce, tuna, boiled eggs, olives, cucumber, salad potatoes. Little pot (left over from weaning days!) of dressing. Not sure how genuine the recipe is, but it works for me.
Cous cous salad - cous cous, lemon juice, parsley, roast pepper/mushrooms/courgette/aubergine, chickpeas.
The frozen jacket potatoes you can get aren't bad at all. Not as nice as a proper jacket spud, but much nicer than a microwaved raw potato.
Homemade soup, piece of cheese, oatcakes
Hummus and stuff to dip in it - nice crackers, posh crisps, carrot, cucumber, cherry toms, peppers
Spanish omelette
