We're almost 4yrs into eating like this, so I feel like I have a good handle on what we can/cannot buy.
Use olive oil in a mister to spray pans on the stove (Pam contains soy)
Williams Sonoma makes a baking spray that is dairy/soy free
Earth Balance (all products are vegan): olive oil spread (now soy free!), regular soy-free spread and baking sticks, coconut spread (good on toast and pancakes); "cheddar" squares, "cheddar" puffs (they're really good!), and they now make a macaroni and cheese
SoDelicious products (referring to coconut milk or almond milk only): yogurt, ice cream, barista-style creamer (boxed, in non-refrigerated section at WF), also creamer in the fridge section
Daiya (vegan cheese, dairy/soy free): I only like the cream cheese. Their other "cheeses" taste NOTHING like real cheese
Trader Joe's British-style English muffins
Archer Farms (Target) take and bake rolls
Middle East Bakery pita pockets (Safeway, WF)
Coconut oil can be used in place of butter or oil for most recipes. Also, the Earth Balance baking sticks
Canned coconut milk or plain coconut milk can be used in place of regular milk for recipes. I don't find that it leaves a "coconut" taste
I use the bread recipe on the bag of King Arthur bread flour- I can post it later if you're interested
Most recipes can easily be converted to dairy/soy free using 1 or more of the above products.
Post again if you have any questions!
