If you are making vegan blue cheese, do that first, here is the recipe for my Vegan Blue Cheese Dressing. Then place in fridge until ready. If you are using store bought, it will come into play when putting the wraps together. In a non stick skillet, heat the olive oil on medium high. Now squeeze as much liquid out of the tofu as possible, just with your hands.(I squeeze mine in a paper towel over the sink). Now, crumble into the skillet. Sprinkle with the salt and if you still have some larger chunks of tofu, break it up with a wooden spoon.
Saute, tossing around with the spoon frequently to cook the tofu through and brown slightly. It will take about 5 minutes or so.
In the mean time, in a small sauce pan, combine the hot sauce and vegan butter. Heat on medium low, stirring frequently until the vegan butter has melted. Remove from heat.
Once the tofu is a bit firm and a bit brown, pour the Buffalo sauce over the crumbled tofu. Stir and cook for another minute or so while the Buffalo sauce coats all of the tofu. Remove from heat.
Let tofu cool for a minute so it isn't blazing hot. Then assemble your lettuce wraps. Pull off the largest and best leaves from the head of lettuce. Place on a platter, scoop a little tofu into the center, then vegan blue cheese if desired, then the chopped celery and green onions. Serve immediately!
