Pour warm water (80-90° F) into a medium mixing bowl. Sprinkle yeast over water and let stand for 5 minutes or until foamy. Add sugar, flours, salt and oil to bowl and stir with a mixer or by hand until a dough is formed. Knead using a dough hook or by hand for 5-8 minutes or until it forms a sticky ball. Cover and let rise for 30 minutes.
Roll dough out onto pizza pan. If dough shrinks back, let rest for 5-10 minutes then roll again. Repeat until it stretches the entire size of the pan.
Preheat oven to 400°F. Bake for 5 minutes.
Drain and rinse beans. Add to a food processor and pulse to puree. Spread onto semi-cooked pizza crust. Shred cheese and sprinkle evenly over beans. Bake 5-7 minutes or until cheese has melted.
Meanwhile, chop tomato, dice avocado and drain corn.
Cut pizza into 8 slices. Top with tomatoes, avocado and corn as desired. Serve with sliced strawberries on the side. (Serving size: 2 slices pizza, 1/2 cup strawberries)
