My staples are...
-milk
-organic yogurt
-whole grain bread (usually 12 grain breads)
-fresh fruits and veggies (try to buy as much organics in these as possible)
-cheese
-organic veg. pasta to make dishes with
- meats (we buy from a butcher who sells clean meats)
-organic gummy bunnies (the kids love these but they are a treat once a week or so)
-whole grain crackers
-organic dried fruits
-organic animal crackers/cookies
-unsweetened apples sauce (or organic apples to make my own sauce)

These are the main staples that are bought every week. They do get things like bear paws too but it's maybe 3 or 4 times a month. I do baking as well so muffins and such.
