I need the Primal Experts' advice.

I have a limited budget for food, but want to 'go' Primal. We have ten people, 2 adults, 3 teens, 1 12 year old, 3 nine year olds and a five year old. Please give me ideas for primal side dishes.

I think I can do main dishes, mostly chicken and ground beef, well enough. I usually serve tossed salad and a steamed veggie and a starch. How can I fill growing bellies without beans, rice and potatoes and without breaking the budget?
