I check the restaurant's nutrional values before going out to eat. "Healthy" is subjective. I focus on calories and consider lower calories healthy because that means less or no oil is used and it's lower in carbs.
You have to be very careful at Sweet Tomatoes even though it's primarily salad. Add-ons, breads, and some soups can trip you up.
Olive Garden has a Garden Fare Menu they don't offer you unless you ask. It has healthier foods than the regular menu.
Applebee's has an under 550 calorie menu.
Chili's has a Lighter Choice menu.
Sonny's salad bar with Brunswick stew is one of our favorites.
However, Thai Ruby is a blue ribbon winner for us! Food appears to be fresh, low calorie, and absolutely delicious....but I can't guarantee healthiness since they don't have a nutrional guide. Oh, please....don't anyone tell me I've been eating high calorie, unhealthy food all this time!
