Roasted Butternut Squash Pizza

I had this amazing pizza at a restaurant and I had to try to recreate it!
Ingredients:
2 cups cubed butternut squash
1/2 sweet onion cut into ringspizza dough
2-3 Tbsp. butter (more for roasting the squash)
2 Tbsp. brown sugar
1 tsp. sugar
1 tsp. olive oil
ground sage
2-3 Tbsp. balsamic vinegar
1/2 cup mozzarella cheese

Toss the butternut squash in some butter, brown sugar and sea salt. Roast at 425 for about 25 minutes or until tender and brown. In a small pan, slowly cook the onions with salt pepper, a dash of olive oil and some butter (just a smige!). Cook slowly to caramelize. Once the onions start to brown slightly, lightly sprinkle with some sugar. Continue to cook down the onions and at the end add a splash of balsamic vinegar. Set aside. In a small sauce pan heat the butter over medium heat and continue to cook util the butter starts to brown. Set aside.
Roll out pizza dough, brush with the brown butter, put on the balsamic vinegar and cheese. Top with roasted butternut squash, caramelized onions and sprinkle with the sage. Bake at 475 for about 9 minutes and enjoy!
