Preheat the oven to 400°F and place a pizza stone on the center rack.
In a small pan over medium-high heat, fry the bacon until crisp. Remove from the pan and crumble.
In the same pan with the remaining bacon fat, brown the chorizo sausage. Remove from the pan and set aside.
Add the sliced mushrooms and onion to the pan and sauté until the onion is translucent and the mushrooms have released their moisture. Remove from the pan and set aside.
Using a small blender, combine the canned yams or sweet potatoes in syrup with minced garlic, two tablespoons of sunflower seeds, a sprig of fresh parsley, and the diced habanero pepper. Blend until smooth, adding more syrup if necessary.
In the same pan, melt the butter over medium-low heat. Pour in the sweet potato sauce and stir until the butter is fully incorporated and the sauce becomes fragrant. Add a pinch of salt and pepper. Remove from heat and let the sauce cool for a few minutes.
Roll out the pizza dough on the preheated stone or a pizza board. Spread the sweet potato sauce on the dough, leaving room for a crust.
Arrange the sliced squash and tomatoes on top of the sauce, then cover with the cooked chorizo, bacon, mushrooms, and onions. Sprinkle with crumbled feta cheese (if using).
Bake in the oven for 15-20 minutes, or until the edges of the crust are golden brown and the center of the pizza has slightly puffed up.
Once cooked, drizzle the pizza with honey and garnish with fresh parsley and the remaining sunflower seeds. Serve the pizza warm as a meal or at room temperature as an appetizer. Enjoy!
