Black Bean Mango Buckwheat Salad
This vegan, gluten-free black bean mango buckwheat salad recipe makes a great lunch or side dish. The zesty lime dressing is extra tasty!

I’m a big fan of grain salads. Grains can be a bit ho-hum on their own, but add a bunch of veggies, and it’s a whole new ball game. And speaking of ball games… This black bean mango buckwheat salad travels well, so you can take it out to the ball game! It tastes good at room temperature, and you don’t have to worry about wilting greens. 😁
Grain Cooking Options
I’ve fallen in love with cooking grains in my Instant Pot. Yes, I’ve been a big proponent of rice cookers, but I have to confess the Instant Pot does a better job. (So, if you haven’t bought a rice cooker yet, you might want to consider an Instant Pot.) Don’t get me wrong. I still use my rice cooker for things like my rice cooker pasta recipe. But if I had to choose between the two, I’d choose the Instant Pot.
The recipe below shares the Instant Pot method and the stovetop method for cooking buckwheat. I referred to a great article by HealWithFood.org on Cooking Times for 30 Grains for guidance.
Buckwheat
I usually make grain salads with rice or quinoa. This is my first time working with buckwheat. I knew it was gluten-free and a healthy alternative to rice, but I was amazed by how quickly it cooks! It cooks almost as quickly as quinoa! I see more buckwheat recipes in my future!
If you don’t have buckwheat on hand, feel free to substitute another grain in this recipe. But be sure to give buckwheat a try in the future. It’s wonderful!

I’ve never heard of Instant pot before. I’m still using a rice cooker so I’ll have to check that out!
I’m obsessed with buckwheat lately and think this would be a great salad to bring to a BBQ this weekend. 🙂
