Skip the mayo and opt for this vinegary German-style potato salad studded with bacon that's delicious warm or cold.
Cook chopped bacon, reserving fat.
In a large pot, bring potatoes to a boil in salted water over high. Reduce to a simmer and cook until tender when pierced with a knife, 15 to 20 minutes. Drain and let cool completely. Cut potatoes into 1 1/2-inch pieces.
In a large bowl, combine bacon and fat, red onion, vinegar, and dill. Add potatoes and toss to combine. Season with salt and pepper. To store, cover and refrigerate up to 1 day.
