Sheet Pan Kielbasa Dinner with a Sweet Mustard Glaze
This has been a go-to weeknight recipe of ours for years. If you can’t find kielbasa, pretty much any big sausage will work- bratwurst, Italian sausage, etc. I love using red onions in this recipe, but if you’ve just got yellow onions- that works fine, too! I do recommend sticking with red, yellow, or orange peppers, though since green bell peppers aren’t as sweet. This is a great freezer recipe. Slice and chop the peppers and onions and store them with the sausage in a large bag, and mix the sauce and freeze separately. We usually serve this with some mashed potatoes or a large green salad.
