Step 1

Preheat oven to 400 degrees.  Line a baking sheet with parchment paper.  Toss sweet potatoes, yellow potatoes, and olive oil together on the baking sheet, stirring to coat.  Season with salt and pepper if desired.  Bake for 20-25 minutes, until potatoes are tender and slightly browned.

Step 2

Meanwhile, in a large skillet, brown sausage over medium high heat.  In the final few minutes of cooking, add the peppers and onions to the pan, cooking until softened.  Set aside.

Step 3

Combine cooked potatoes with sausage/pepper mixture.  Serve immediately or cool and refrigerate.
