Place a large non-stick pan over medium-high heat and add 1 tsp. olive oil.
Add ground pork, butternut squash, and a pinch of salt and pepper to hot pan. Stir occasionally, breaking up pork with a spoon, until squash begins to soften and no pink remains on pork, 5-7 minutes.
If using ground beef, cook, breaking up meat, until no pink remains, 4-6 minutes.
