Balsamic Caramelized Onion & Asiago Focaccia

This was actually quite sweet, even for my tastes!

Ingredients
4 tsp olive oil, divided
½ C choped onion
1 T honey, divided
½ t fresh thyme (or pinch dried)
1 T balsamic vinegar
1 t salt, divided
1 t yeast
½ C warm water (~105)
1¾ C flour
1½ oz grated fresh Asiago cheese

Directions
Heat 2 tsp oil in a skillet (medium heat). Add oinion nad thyme, cooking until onions are translucent and browned. Remove from heat, stir in half the honey (1½ tsp), balsamic vinegar, ½ tsp salt. Set aside to let cool.

Dissolve yeast with remaining honey in the warm water. Let stand 5 minutes until yeast begins to bloom.

Add half the flour, remaining 2 tsp oil, remaining ½ tsp salt, and onion mixture; mix until soft dough pulls away from the sides of the bowl. Continue kneading and adding additional flour as needed until dough is smooth and elastic and barely sticks to your hands (7-8 minutes)

Place dough in large bowl coated with oil (or non-stick cooking spray), turning dough to coat. Let rise in a warm place until doubled in size (about an hour).

Punch dough down; let rest 5 minutes.

Gently press dough into a ¼ sheet jelly roll pan (or 9x13 pan) lightly coated with non-stick cooking spray and/or lines with parchment. Cover; let rise in a warm place until doubled in thickness (about 25 minutes).

Preheat oven to 400°. Sprinkle with cheese; bake 20 minutes or until golden brown on top.
