I think I’m starting to develop a sheet pan dinner obsession.

Is that a bad thing, do you think? My guess is likely that no, not a bad thing at all. I’m also willing to guess you’re with me on this. Right?

Because truly, how can it be a bad thing to enjoy what is basically the perfect weeknight dinner recipe? Toss delicious ingredients on a pan. Season appropriately. Place in a hot oven until cooked. Eat.

Could not be easier, and I love that so, so much.

This sheet pan dinner features plump, juicy, smoked kielbasa and is my play on the old Italian standby, sausage and peppers. Did you know smoked kielbasa and sweet, slightly spicy peppers goes awesome together? If you do, you’re probably from the Midwest and know Polish-Americans. Just saying.

I love the combo of heat, sweet, and spice in this sheet pan dinner. You’ve got crispy sweet red peppers, yellow onions, smoky kielbasa, all covered in a 3-ingredient mustard glaze that’s also perfection as a salad dressing. So while you’re at it, make a big, leafy salad and toss it with the remainder of this sauce. Serve some crusty bread on the side and you’ve got a dinner in 20 minutes that’s full of flavor and a bit of bite.

See why these sheet pan dinner recipes are my new thing!? They’re too crazy easy not to be!
