Watermelon in the summertime, ever heard of it?
So classic it’s almost cliché, but hey, clichés stick around for a reason—they just work. And even though the fruit is great to eat straight out the melon, it’s even better in a watermelon SALAD. So I decided to whip up a super unique Sweet Mustard Quinoa and Watermelon Salad recipe for you all. You’re very welcome. And did I mention that it’s vegan? Oh, not yet? Well, it is. A super delicious vegan watermelon salad for your eating pleasure.
This vegan watermelon salad is WILDLY easy to make and definitely a unique take. The dressing is spicy and sweet at the same time—think honey mustard vinaigrette flavor, minus the honey (because vegan, duh). The addition of quinoa makes it not only delicious, but higher in protein and more satisfying than your average watermelon salad.
Cook. Toss. Eat. Enjoy.

Cooking Quinoa 101
If you haven’t learned your quinoa ABCs yet, my pantry page has you covered with some of its most admirable qualities. Now let’s talk about how to cook this high protein, gluten-free grain.
You can cook quinoa in water, non-dairy milk, or broth depending on what you’re using it for. In this case, I’d recommend a vegetable broth for some added savory flavor. Think non-dairy milk for more breakfast-y type recipes for added creaminess. Whatever liquid you’re using, one part quinoa to two parts liquid is a safe bet.
Always rinse your quinoa well before cooking! The outer bits of quinoa can cause a touch of bitterness if you skip this step—not welcome here.
Let’s get cookin’:
- Mix quinoa and liquid in a pot (in this case: 1/2 cup quinoa and 1 cups broth or water)
- Bring mixture to a boil uncovered on medium-high heat
- Once you’ve reached that boil, cover the pot and reduce heat to low
- Simmer for 15 minutes or until all the liquid is absorbed
- Remove from heat, uncover, and fluff that quinoa with a fork!

I’m not the only one out here making watermelon salads and though you will LOVE my vegan Sweet Mustard Quinoa and Watermelon Salad, there is enough love to go around. I’ve encountered some seriously badass watermelon salad recipes lately and I just can’t keep them a secret.
You know how fruit salad tends to turn into something more like…fruit soup? Not so with this one. This watermelon berry salad is topped with a lime mint dressing for a totally elevated take on a classic side.
If you’re looking for lunch, this balsamic watermelon chicken salad is a must-try. While it’s obviously not vegan-friendly, it is delicious-friendly, fresh, and filling.
I could probably list another 50 watermelon salad recipes I love, but let’s be honest—neither of us have time for that. HOWEVER, we all have time for one more and it MUST be none other than this grilled watermelon salad. It’s made with donut peaches and balsamic reduction, but did you hear that first part? GRILLED watermelon. What a world, y’all.
That’s it for my watermelon salad shout-outs today. Feel free to share some of your own! xo.

Haley, this salad is amazing!! I just finished a bowl right now. Easy to make, and such an unexpected mix of flavors. I’ll be making this every week until watermelon are out of season. 5 star recipe! (I can’t figure out how to rate this, though, maybe because I’m on my phone?) I’ll for sure rate this when I figure it out because it deserves all the love and recognition!
Haley says
YOU ARE AMAZING. I’m so glad you loved it as much as I do! xo.

I love this! Can you believe I only tried watermelon in salad for the first time only a couple of weeks ago on holiday? Anyway, I fell in love so must try this. Great idea making it as a way to use up leftover quinoa too. Will pin & share!

I thought I was the only human who didn’t like watermelon so I’m happy to hear you have friends who don’t like it either haha! Buuuuut every other bit of this salad sounds so incredible!!
Haley says
Haha. You are not alone! But I’m glad you looked at the salad anyway, because it tastes really great even without the watermelon. And maybe you could add a fruit you like to it? I think peaches would be really great in this. (I don’t know if you like those, but it’s just a thought!) ENJOY!
