We love this combination of ingredients and flavors! So delicious.

I will be making this for Thanksgiving dinner. I was never a fan of red onion, so my question is... what would compliment this dish the beast as a substitue for red onion, shallots or yellow onion?


Tuesday 20th of November 2018

Personally, I would go with shallots. Yellow onion, eaten raw, can be overpowering. Shallots will be milder and will complement the salad nicely. Great question. Thanks for asking and enjoy the salad!! Happy Thanksgiving, Terri!!

omg this salad is the stuff my fall dreams are made of!! There's nothing not to love about this and it's a must-make for Thanksgiving and any other fall gatherings!


Tuesday 9th of October 2018

I agree! Glad you've enjoyed this recipe! Thanks.

Amazing flavors! I could make a meal of just this!


Tuesday 9th of October 2018

LOL. I can, and I have!


Monday 8th of October 2018

This sounds delicious and just what I need to add to our holiday menu. It cooks up a lot faster than roasting the vegetables in the oven and that's a plus. And I bet the crispy onions and pumpkin seeds on top would be the perfect touch.


Monday 8th of October 2018

I wish I would have thought about the crispy onion topping or the pumpkin seeds before I wrote the post. LOL. Next time.
