Combine flour, water, salt, cumin, thyme, garlic and 1 1/2 tablespoons of the olive oil in a bowl. Let the batter rest for 2 hours, covered, at room temperature.
Then preheat your broiler. Add the remaining tablespoon of olive oil to a 10-inch skillet and heat the skillet in the oven for 4 minutes.
Then remove the skillet from the oven and pour the batter into the skillet. (You may use half the batter and make two if you prefer a thinner flatbread)
Broil for about 8 minutes. Slice and serve.
The French sprinkle their socca with salt and pepper, drizzle it with olive oil and eat it off a napkin. You can serve it with your favorite toppings. Spread pesto sauce on it, Mediterranean salsa, or brown gravy (gluten free gravy recipes here.) or whatever you like.
Your approximate preparation time is only 5 minutes, but allow 2 hours for the batter to rest.
