To clean mushrooms: pop off stem and using a spoon scrape out black gills (best to do this over a sink or trash bag). The using a wet cloth, wipe the mushroom caps clean.
Add 2 teaspoons of olive oil to a nonstick skillet, add 2 mushrooms, cap side down.
Heat for 3-4 minutes, flip and cook additional 3-4 minutes or until tender. Repeat with remaining oil and mushrooms (or use large grill pan to do all four at once).
Remove to a small baking dish. Sprinkle each mushroom with a little salt, pepper and a couple shakes of oregano, basil and red pepper flakes (optional). Top with ¼ of the sauteed spinach, ⅓ cup of tomato sauce and 1 slice of mozzarella cheese.
Place under broiler for 2-3 minutes or until cheese is melted.
For sauteed spinach:
Heat a drizzle of olive oil in a large pot over medium-low heat, add minced garlic and cook for 30 seconds. Add spinach and toss with tongs until starting to wilt, 3-4 minutes. Season with salt, pepper and a squeeze of lemon juice (optional).
For Tomato Sauce:
Add olive oil to skillet over medium heat. Add onion, bell pepper, garlic and red pepper flakes, saute until soft, 4 to 5 minutes.
Add crushed tomatoes, diced tomatoes, dried oregano, sugar and bring to a boil then reduce heat to low and simmer for 10 minutes. Season to taste with salt and pepper. Makes ~7 cups of sauce. Freeze leftover sauce in small portions or cut recipe in half if desired.
