Lunch here is generally sandwiches or wraps.
Sausgae rolls
pasta with tuna peas and corn and cheese

Things I find easy to add veg too and cook in large amounts to last a few meals or feed lots are:
Spag bol and next day I make a pasta bake from left overs
Risotto (chicken, onion, capsicum 2 colours, peas, corn, carrot grated, mushroom, bacon)
Lasagna
Left over roast lamb I make shepards pie
SLOW COOKER
Chicken curry
lamb shanks
beef stroganoff
