How much mashed potato do you need to make? Obviously lots cos we'd get heaps in a 6 cup pot, lol!

Any of the above (my vote is with potato bake ) or

Roasted mixed veges tossed with olive oil, garlic and mixed herbs,
Rice with veges through it,
cous cous with finely diced carrot, capsicum, peas, herbs etc cooked in stock.

Or what about just plain mixed steamed veges?
