Traditional sausages without grains, soy or other junk are good. Otherwise, not.
Mash is not ideal under Primal. However, more and more of us eat potatoes.
It is generally recommended to avoid snacking by getting enough protein and fat at meals so that you don't get hungry in between. Cashews and chicken are better than most snacks people eat.
Be careful with the fruit.
Being on your feet, moving at whatever pace is good.
Welcome to Primal. Good luck.
