Evenly distribute clean mushroom caps gill side down on a lined baking sheet. Roast for 10 minutes, until mushrooms are soft.
Remove from the oven and carefully flip the mushroom caps over. If water accumulates on the baking sheet, drain the liquid.
Spoon the tomato sauce into the mushroom caps. Add cheese and broccoli (or other veggies). Return to the oven for another 10 minutes, or until the cheese is fully melted. To brown the top of the cheese, broil for the last 2 minutes.
Remove from the oven and sprinkle with oregano and basil. Serve immediately. Enjoy!
