Preheat Your Oven: Place a pizza stone or baking sheet on the center rack of your oven and preheat to 425°F / 220°C. 2.
Sauté the Veggies: In a large skillet, melt 1½ tsp. of the margarine over medium-high heat.
Add the sliced mushrooms and cook, stirring frequently, for 4 to 7 minutes until they begin to brown.
Add the broccoli florets and ⅓ cup of water.
Cover the skillet tightly and steam for 3 to 4 minutes, until the broccoli is tender-crisp. 3. Make the White Sauce: While the veggies cook, melt the remaining 1½ Tbs. margarine in a small saucepan over medium-high heat.
Whisk in the flour and cook for 2 minutes, stirring constantly, until it turns a pale golden color. Gradually whisk in the milk, minced garlic, and salt.
Continue cooking and stirring for 3 to 4 minutes until the sauce thickens and just begins to boil.
Remove from the heat and stir in ¼ cup of mozzarella and 2 Tbs. of Parmesan until the cheese is fully melted and the sauce is smooth. 4. Assemble the Pizza: Carefully shape your pizza dough according to the package . Cautiously remove the hot pizza stone from the oven and place the shaped dough directly onto it. 5.
Top and Bake: Spread the creamy white sauce evenly over the dough, leaving a ½-inch border around the edge.
Arrange the cooked broccoli and mushroom mixture over the sauce.
Sprinkle the remaining ¼ cup mozzarella and 2 Tbs. Parmesan over the top.
Bake for 18 to 20 minutes, until the crust is golden brown and the cheese is hot and bubbly.
Let it cool for a few minutes before slicing and serving.
Preheating your baking stone or sheet is the key to achieving a perfectly crisp, non-soggy crust.
Don't overcrowd the mushrooms in the pan.
Cook them in batches if needed to ensure they brown properly rather than steam.
Pat the cooked vegetables dry with a paper towel before adding them to the pizza to prevent excess moisture.
