These look amazing. If the dough is workable enough, tightest I can get for a roundish (round or fat oval) loaf is:
Flatten slightly into a rectangle, so a short side is at top and bottom. Fold that in thirds into a smaller rectangle, (fold the top down to the middle then the bottom up all the way to the top) then repeat but in the other direction (like, side to side) and more tightly, tucking in the ends and pinching the seam.
I don't know if it's the best way, but it's the best way I can actually accomplish with my two hands.
Slow cooker, on the back porch, if making a batch of them. Otherwise just low & slow in the skillet. A comment farther up says 'many recipes call for sugar' but I have never seen that. The onions that make your eyes water when you cut them, and a little salt & olive oil.
