This vegetable salad with dijonaise recipe is perfect for summer! It is a healthier and more flavorful riff on the American classic potato salad. This combo of roasted white sweet potatoes, cauliflower and grilled summer squashes is super tasty. I love the fresh pop of dill and the tangy drizzle of dijonaise. Bring this to your Memorial Day or Fourth of July cookout and it is sure to be a hit.
What is dijonaise?
Dijonaise is a creamy and tangy dressing made by mixing dijon mustard and mayonnaise. In this version I use vegan mayo. Dijon is a hugely flavorful mustard that combines brown mustard seeds and white wine plus other ingredients that can vary. I love using dijon in my marinades and dressings because it gives them a really distinct tang. In my opinion dijonaise is the best of both worlds with both the creaminess of mayo and the zippy taste of mustard combined. Drizzled over a summer salad or on a burger is a dream.

HOW TO MAKE Vegetable Salad with Dijonaise
This salad is easy to make even though there are three cooking processes needed. The first process is roasting the sweet potatoes and cauliflower in the oven. The beauty of this is that you may simultaneously grill the squash and zucchini without worrying about the roasting veggies. To simplify this recipe further, cook the squash and zucchini on a sheet pan as well.
Here is the most efficient method of executing this delicious summer salad.

Love love love this idea! It's classic enough to be approachable, yet nourishing enough to please more health-focused eaters. This would be so perfect for a Memorial Day BBQ on the deck!

Great marinade for the zucchini and squash - don’t skip it. I used a grill pan on the stove, worked well. Double the recipe and keep the sauce separate so you can microwave some of the veggies to quickly round out other meals as needed.
Sara Tercero
Thank you for the 5 star rating! I love this one too. That marinade works for everything!
Jean
I'm wondering what *type* of squash. Acorn or butternut ok? Zucchini is a type of squash, also.
Sara Tercero
Hi Jean, yes zucchini, yellow summer squash, goldbar squash are the best types for this recipe. Acorn and butternut would also be delicious but would need a different preparation method.
Trenya
How much dill?? It's not listed in the ingredient list.
Sara Tercero
Hello Trenya, sorry about the typo! This is an older recipe, I am surprised it hadn't been called to my attention! I have fixed it to say 3tbsp fresh dill. Use more or less depending on your preferences.
