- In a bowl, combine all of the ingredients. Season with salt and pepper. Set aside.
- With the rack in the middle position, preheat the oven to 425°F (220°C). Line a baking sheet with a silicone mat or parchment paper.
- Place the naan breads on the baking sheet and cover with the sauce. Top with the mushrooms, sausages, bell pepper and cheese.
- Bake for 10 minutes or until the cheese is slightly golden. Garnish with basil, if desired.
Wheat sausages (seitan) are available in some grocery stores, often near the refrigerated tofu.
To make this recipe vegan, the cheese can be replaced with a vegan cheese substitute and the naan breads (which often contain butter or buttermilk) can be replaced with Greek pitas.
