Cornish pasties, pies, curry, chilli, in fact the choice is yours if you have a microwave. But if that is going to be a bit much, don't dismiss sandwiches too quickly - especialy if you do the same filling (s) and bread day in day out, - ring the changes with crusty/soft rolls, brown/granary/white/ rye bread, or try using tortilla wraps or fill pitta breads. Crispbreads, pate, cheeses, dips, chicken drumsticks roasted with various flavours - eg herbs and garlic or BBQ take a salad box or coleslaw or potato salad
