First step is to decide what flavor profile you want your bowl to take. This decides what additional spices you will use and what sauce to put on top, if you use one. For a mexican-american flavor, I used cumin, paprika, and garlic and this turned out well. I then drizzled some chipotle Bitchin' sauce ontop.
The next step will be to cut up the sweet potatoes. Dice these into ~1/2 inch wide pieces.
Place the sweet potatoes on a greased baking sheet and season with salt, pepper, and your other spices. Bake at 425 F for ~30 minutes, until tender, flipping every ~10-15 minutes.
Next, cook the chickpeas on the stove in a pan over medium-high heat with either oil or water, salt and pepper, and any other spices, for ~5 minutes, until lightly browned and some chickpeas begin to 'pop' out of their shells. Set aside.
Chop the bell peppers.
Cook the peppers in a pan on medium heat for ~7 minutes until they begin to soften, then add the frozen vegetables and cook for ~7 more minutes. Set aside.
