Start by making the pizza dough in a large bowl. Mix together yeast, sugar, and warm water. Let it sit for about 2 minutes until the yeast is coming to the top and it looks like it's bubbling a little.
Add in the salt, olive oil, and flour. Mix together. Cover and let it rise for about an hour. The pizza dough should double in size.
While the pizza dough is rising, chop the cauliflower into small pieces, carrots, garlic, and green onions. Grate the ginger.
In a small bowl add peanut butter, soy sauce, sesame oil, sriracha, garlic, ginger, water, brown sugar, and lime juice. Mix together with a fork or whisk.
Preheat the oven to 400 degrees. In another small bowl, mix together the chopped cauliflower and 1/4 cup of the sauce.
Bake the cauliflower sauce mixture in the oven for 20 minutes.
While the cauliflower is baking, roll out your pizza dough into a circle on a pizza pan or on a baking sheet.
Spread the sauce evenly on the pizza dough, add the carrots, and add the cauliflower when it's done baking.
Lower the oven to 375 degrees. Bake the pizza for 27 minutes until the edges are golden brown.
Take your pizza out of the oven top it with chopped green onions to serve.
