Request it to not be cooked in Vegetable Oil, Soy Sauce(unless GF) or Fried.
Request Real Butter, be sure to clarify that Margarine is NOT real butter.(yes this has been a repeated required explination)
Potato- mmm.see Real Butter requirement.(dont eat the skin)
avoid gravies(wheat) and most dressings(vegetable oils, blech) unless they can clearly list ingredients.
Some of my favorites eating out:
Outback: Steak Big one, Medium Rare. Potato with Cheese and Butter(im lacto-paleo) Steamed veggies(usually broccoli/cauliflower/carrots)
psuedocheat: they have a gluten free dessert Chocolate Thunder down under. wayy too much sugar :)
Carrabas. Chicken Caesar Salad, no croutons.
Any Japanese Teppenyaki: bring GF Tamari if they dont have it available to cook with.
Local Chinese. Discuss with them that you are GF, otherwise they can handle.
PF Changs: has a GF Menu, just watch for the heavy vegetable oil use.
Chipotle: watch the veggies, cooked in heavy soybean oil. you can request fresh veggies no oil at most locations if youre willing to wait a few minutes(you should!)
Mexican: Fajita plate sans shells.
Sushi. be careful of the fake crab sticks, they have wheat in them, very minimal, but its there.
BBQ: All Day Pulled Pork can be amazing, question them about sauce ingredients, sugar content is often thru the roof. sometimes they use thickeners. I get a pound of pork at a local place, vinegar based sauce, never have leftovers. so good.
Sams Club: my 2 local ones, and I presume now everywhere, now have Gluten Free Rotisserie Chickens for $5. Easy Grab and go GF Paleo meal.
Longhorn: Flo's Filet, steamed veggies, baked potato.
Ted's montana grill: Buffalo!
so many of the big chains have GF Menu's now... just make sure that youre checking what they are using to cook with. Dont blow a healthy meal with a bolus of vegetable oil.
Edit: Moes now has Grassfed Steak and gluten free labeling!
