Instructions
- Place a medium or large skillet over medium-low heat, once heated add 2 tbsp olive oil. Thinly slice one and a half small white or yellow onions. Saute the onions in a skillet for 45 minutes, stirring the mixture every 2-3 minutes. The end result should be deep golden brown, soft, sweet onions.
- While the onions are cooking, slice the mushrooms. Take the caramelized onions out of the skillet and add the mushrooms, along with a pinch of salt and pepper and the dried thyme. There should be some residual oil in the skillet to cook the mushrooms, if not add a tad more. Cook the mushrooms until all of the moisture has evaporated away (about 10 minutes over medium heat).

Then sprinkle the caramelized onions and sauteed mushrooms over top of your sauce. Then add the cheese of your choice and cook according to my pizza dough instructions.
