Introduction
There's something about pork and peppers that just works. It's simple, savory, and deeply satisfying without being heavy. This version leans into bold flavor with sweet peppers, garlic, tomato paste, and a little punch from pepperoncini. It's the kind of skillet dinner that feels rustic and intentional - but comes together in under 40 minutes.
The pork tenderloin stays tender thanks to a quick sear and a short simmer in a lightly tangy broth. The peppers soften just enough to sweeten, while the pepperoncini bring brightness that cuts through everything beautifully. It's balanced, high-protein, and easy enough for a weeknight without feeling rushed.
