Whole30 Baked Peppers and Onions is one of the easiest dishes you'll ever make! Once the vegetables are prepared, just toss them in the spices, and bake right in a cast iron skillet. It's great for fajitas, burrito bowls, or even meal prep!
Start by adding sliced peppers and onions into the cast iron skillet or a bowl. (If it's easier to stir.) Pour over all the spices and olive oil, and stir well.
Bake the peppers and onions in the cast iron skillet for about 30 minutes at 350 degrees, or until vegetables are tender. (Stir halfway through.)
