Lentil – Quinoa Burger with Grilled Onion

The season of outdoor and BBQ dining is in a full swift, at least here in North America, Canada just celebrated National Holiday on the 1st of July and our in U.S are celebrating Saturday, the July 4th. This is why I feel that this is a perfect time for a new veggie burger recipe.

Altough, I know there is so many veggie burgers on the market now days, which is great! Nevertheless, this yummy and super healthy Lentil – Quinoa Burger is for those of you who prefers to make them at home from scratch. You can also check my recipe from last year that I made many times before. It is the delicious BEET BURGER. They are both low in fat, high in protein and obviously, zero cholesterol!!!

Oh, and if you are wondering about the double burger on the photos, don’t worry, I didn’t eat it that way. But of course, feel free if you think you can do it, lol. I though it would be cool to do the photoshoot like that. What do you think? Not to forget, my favorite part is the grilled onion! Yum! And if you would like to know what is the sauce, I will led you on the secret.

I had leftover tomato sauce and cashew sauce from my HEALTHY SPELT PIZZA. I just added little bit of mustard into the cashew sauce, mixed well and drizzled on the burger. It was a mouthwatering bite and I hope you try! Thank you for visiting and I would love to hear your feedback.
