Step 1

In a large pot, cover diced potatoes with cold water by about 1-inch. Bring to a boil then reduce heat to a simmer. Cook, uncovered, for about 5-7 minutes, until potatoes are fork tender. Drain the potatoes and rinse with cold water. Set aside to cool to room temperature, then transfer to a large bowl.

Step 2

Meanwhile combine the mayonnaise, mustard, hummus, vinegar, salt & pepper in a small bowl or large measuring cup. Whisk together until smooth.

Step 3

To the bowl with the potatoes, add the celery, red pepper and relish. Pour the mayo mixture over top and stir until everything is evenly coated. Add more salt & pepper if desired. Serve immediately or refrigerate for up to 2 days in advance.
