  1. Loved the caramelized onion! Delicious-don't change a thing! In fact, DH had seconds which is unusual. The ratio of dressing to potato is spot on. I subbed in red wine vinegar b/c I did not have cider vinegar and used a red onion-- caramelizing it on top of stove at medium for about 15 minutes. A wonderful make ahead for a hot day! Thanks Kim127 for a keeper. Made for PRMR game.
  2. Excellent potato salad! Who would've thought that grilling the onions would make such a difference. I added 14t garlic powder, 1.5t yellow mayo and three chopped eggs. Might have had a bit more grilled onion that I grilled on a hot skillet on the stove. If you're not in the "like mustard" group, I believe you'd love the salad anyway.
  3. This was a really good potato salad but DH & I like a few more goodies than just onions, celery & potatoes. So next time, I'll probably add more celery, cukes, & hard boiled egg. Yes there will be a next time. Really like the flavor of the grilled onion. Enjoyed this with bean salad & a lovely thick loin lamb chop. Great meal. Thanks for a great recipe Kim, the only reason for 4 instead of 5 stars is the lack of extra goodies. Made this for ZWT5.
  4. Roasting the onion made this AMAZING. I used reduced fat mayo and skim milk to fit in with our WW points and it turned out beautifully. We also like the skin on our potatoes, so I chopped them skin on then boiled them. I also tossed in some chives from the garden. This is a favorite. We will make it again. Reviewed for ZWTIII
  5. This was very nice! I roasted the onion in the oven, and the flavor made this salad! I thought the dressing might be too wet, but it was perfect. Thank you for a slightly different, yet lovely potato salad!
