Preheat the broiler on your oven
Thinly slice the al fresco chicken sausages
Lay pizza crusts on baking sheets covered with parchment paper (optional, but the paper helps transfer pizza to cutting board later). Don’t crowd the crusts, use two pans and two rounds of baking if needed.
Spoon or drizzle taco sauce liberally onto pizza crusts - no need to get full coverage.
Divide cheese evenly between pizzas, and sprinkle half of each portion over the sauce.
Layer chicken sausage slices onto sauce, with a little space between each slice.
Add olives and jalapeños to taste.
Sprinkle remaining cheese over all. Add a few more drizzles of taco sauce.
Place pan into oven on low broil. Broil 3-4 minutes.
Check frequently as the cheese can burn quickly. When cheese melts and turns a light brown, turn off oven and remove pan.
Let cool 1-2 minutes. Slice diagonally into wedge shapes with a pizza cutter.
