This Vegan Potato Salad with cauliflower, chickpeas, & zucchini has the volume turned up since we are roasting all the vegetables together. It all gets tossed in a vegan sour cream and onion dressing that soaks into all those roasted veggies. Vegan & gluten-free, it is the best side dish for summer BBQs and picnics!

Vegan potato salads are a must for summer BBQs and picnics. Instead of all the mayo that spoils up easily, here is a vegan sour cream version with tons of flavor. It also has cauliflower, chickpeas, and zucchini and really can be the main if there is nothing else to eat :).

Another cauliflower recipe you say. Well you know roasted cauliflower is fabulous any time of the year. You can make this salad without the cauliflower too. Just potatoes, chickpeas, and zucchini in a creamy dressing. the bland summer potato salad, be gone! This Vegan potato salad has roasted veggies and a load of flavor! Potatoes and cauliflower are roasted to a crisp brown, the chickpeas and zucchini are roasted lightly to golden, tossed in dressing, topped with fresh herbs. 

I had the Follow Your Heart Vegan Sour Cream sitting the fridge for days now for review. I hardly ever use packaged sour cream, cream cheese, and other condiments. Sometimes, though, they do come in handy for a quick fix. Follow Your Heart sour cream is creamy and delicious. With a little help, the taste and texture shine through.

    Outstanding!! I used the sour cream recipe to make the dressing and it turned out amazing. I might try it with a tofu sour cream next time just to compare but I will absolutely be making this again.

    A summer must in our house! Love the flavor. I hv made your homemade sour cream and also used a tofu sour cream, both great. Added some fresh parsley and green onion before serving recently and loved that!
