Place the chopped sweet potatoes on a baking sheet.
Stir together the tamari and smoked paprika in a small bowl and pour over the sweet potatoes, tossing to coat.
Bake at 400° for 30 minutes.
While the sweet potatoes bake, cook the onion and garlic in a large skillet over medium heat until the onion is soft. If it begins to stick, add a little water to the skillet.
Add the bell pepper and mushrooms and continue to cook several more minutes, until the bell pepper is tender-crisp.
Add the spinach to the pan and cover the skillet, allowing the spinach to begin to wilt.
Stir in the chickpeas, balsamic vinegar and hot sauce.
Season with salt and pepper.
Serve the sweet potatoes topped with the other vegetables and chickpeas.
