Here's what I used that was store bought:
~1 bag of whole wheat pizza dough (enough to make one large pizza pie) from Trader Joe's
~1 jar pizza sauce from Trader Joe's
~Vegan cheese (I only had cheddar in the house, but it tasted great); I use Follow Your Heart.
In a food processor I coarsely chopped (amount is estimated):
~2 handfuls of baby portabella mushrooms
~4 tablespoons of sun dried tomatoes (in oil)
~1/3 bag of fresh spinach
~2 handfuls of fresh broccoli florets
~2 handfuls of pine nuts
~salt, pepper, garlic powder and basil (to taste)
On a floured surface, I rolled out the dough and separated into four pieces. I scooped the mixture onto one side of the dough. I really piled it on. I added on top:
~shredded cheese (I shredded about 1/3 of the block of cheese for all 4 calzones.)
Then I folded over the dough and pinched it closed. I placed the calzones on a non-stick pizza pan and squished them making the calzones more flat, which expanded their surface area.
In a small bowl I combined olive oil and garlic powder then coated the tops of the calzones with this using a brush.
I baked them at 425 degrees for approximately 15 to 20 minutes. I took them out when they became slightly brown and no longer doughy.
I served them with:
~pizza sauce (warmed up first) poured over the top.
~sliced avocado and tomato on top with salt and pepper to taste.
