Prepare yeast mix: In a small bowl, add warm water and honey. Mix to dissolve. Sprinkle yeast in. Mix to dissolve. Set aside for 5-10 minutes to activate. It will get foamy on top.
Mix dry: Mix dry ingredients in large mixing bowl to combine.
Mix wet: Lightly whisk eggs and olive oil together in a small bowl.
Mix together and form a dough ball: Add egg mixture and activated yeast to the dry ingredients and form a dough ball. Transfer ball to an oiled bowl, cover with dish towel and set aside in a warm place (70-80 F is ideal) to rise for 1 hour. It will not double in size, but it will rise a little.
Prep toppings while dough rises: Remove stems from rapini, boil until tender and drain. Grab two stove-top pans and saute 1 sliced garlic clove in 2 tbsp avocado oil, in each pan. Add rapini to one pan and mushrooms to the other. Season each with sea salt and coat in oil and garlic. After a few minutes remove rapini and set aside. Add some red or white wine (other liquids work too) to the mushrooms and cover for a few minutes. Remove when liquid evaporates and mushrooms are cooked. Set aside.
Once dough has risen, preheat oven to 550 F. Preheat pizza stone, baking sheet or metal pan.
Roll and shape dough: Place the dough on parchment paper. Place a piece of parchment paper over the dough (if necessary) and shape dough with your hands by pushing down (on top of parchment, so it doesn't stick) and roll with rolling pin. Flatten your pizza about 1/8-1/4 inch thin. Roll the crust thick or thin (to your liking) by shaping with your fingers and rolling the edges. Use extra cassava flour if dough is sticking. NOTE: Split the dough in half before rolling it out to make two smaller pizzas.
Add toppings: Add tomatoes, rapini, mushrooms and sausage onto the dough. Lift the whole piece of parchment paper with pizza on top and transfer to the preheated baking sheet.
Bake in the oven for 8-12 minutes until dough is firm and slightly golden, pulling out halfway and removing parchment paper. For a crispier golden crust, allow a few more minutes. Allow more time if cooking at lower temperature.
