Spray a medium-size skillet with cooking spray and heat over medium.
Add sausage to hot skillet and season with salt and pepper as desired; cook until no longer pink, stirring frequently to crumble.
Meanwhile, chop mushrooms, bell pepper, carrots, broccoli, and pineapple into smaller pieces.
Divide pizza dough into 4 equal portions so each family member can assemble individual pizzas. Roll the dough out to the desired thickness and place onto large baking sheets for assembly.
Top each pizza with sauce and toppings as desired; encourage everyone to try something new!
Bake for 8-10 minutes until crust is golden and cheese is bubbly.
