Optional: If you are using garlic, finely mince garlic and saute briefly in medium hot skillet with some olive oil.
Meanwhile in a mixing bowl, combine flour, baking powder and salt. If you have sauteed garlic or onions to add to the bread, this is a good time to add them. Add yogurt. Add olive oil as needed for a nice soft, easy to use dough.
Heat cast iron griddle or skillet to medium high heat (5 on my gas stove).
Divide dough into 6 portions. Roll each portion into a ball, then roll out flat into a circle, 1/8" thick or less.
Brush a little olive oil onto skillet or griddle and add a flatbread. Cook 1 minute on each side, then remove to a dinner plate and keep covered with clean dish towel to keep warm as you finish with the remaining flatbreads.
While it is cooking, you can be rolling out the next flatbread and cook as described above until all are cooked.
This would also be good with seeds added to the dough, such as caraway, fennel, sesame, finely chopped sun dried tomatoes, and/or with garlic or onion, minced and sauteed, then added to the flour mixture. The seeds can be added to the dough, or sprinkled on top of the dough as you are rolling it out into rounds, then use the rolling pin to press them into the dough as you are shaping it.
Although spelt is an ancient form of wheat, it is safe for most people with wheat allergies. It does, however, contain gluten. If you know you have a wheat allergy or wheat intolerance, eat at your own discretion.
