What i do with mince and veges. Generally 300 -400gram mince i reckon would easily do family of 4 or 5 or more, depends on how much vege you use (and how much you eat!). I prob use about 4 cups veges all up, plenty for us 2, and the dogs, and my lunch for the next day.
Cook mince & a diced onion with abit of salt & curry powder. When just about cooked, chuck in 1 cup of rice, and a packet of chicken noodle soup mix (i just use the home brand one). Cook for a min or so, till rice absorbs meat juice, and then add water. Keep adding water till rice cooked, but, little bits at at time, dont want it to go soupy or glugy. I cook in wok, with lid.
While your cooking that, cut up veges. I use generally red & green cap, and carrot. Chuck all that in as you go along, depending on how cooked you want it. Then near the end, chuck in mushrooms and cabbage, and leave lid on till cabbage and mushies are softish.
Can also flavour with some soy sauce or worchester sauce.
We serve ours with chilli and garlic sauce.
My mum used to cook it when we where kids - cheap feed. Called it chow mein.
DH's mum also cooked it, but called it Green Rice.
