Never deviating from your standard recipe
Do you make your potato salad, in the same way, every time? Everyone has their favorite recipes, but that doesn't mean you shouldn't branch out and try something new. For example, to keep things vegan - and interesting - why not add some peas and avocado to your potato salad? Your salad may turn out greener than usual, but you may find that you prefer it this way anyway. How about a carrot and cucumber-based Korean potato salad? It's an excellent way to include more vegetables in your diet.
Of course, when trying to shake things up, you don't have to go completely off the rails. You can always take the easier path. If you've never tried mustard in your potato salad, now's your chance. If you always use white onions, try substituting red onions or scallions. You can also substitute pickles for the celery for added crunch. There are so many different ways to make potato salad that it should be treated as a blank canvas.
