Preheat oven to 350°F (180°C).

Heat oil in a small skillet over medium heat. Add mushrooms and some salt and pepper. Cook until mushrooms have softened, 5-7 minutes. Remove from heat and set aside.

Place naan on a foil-lined baking sheet. Spread pizza sauce evenly on the naan and swirl in the garlic powder, Italian seasoning, and crushed red pepper (for no heat, omit the crushed red pepper).

Sprinkle cheese, mushrooms, onion, and bell pepper on top. Bake until onions are translucent and edges are crispy, about 10-15 minutes.

Slice pizza and serve.

Mix ingredients together in a bowl and serve.

If you want to prepare multiple servings in advance, you can shred the carrots and lettuce and slice the onion in advance and store them in the fridge in a ziploc bag or tupperware container so you just have to dice a little cucumber and tomato and add a little dressing the next time.
