National Veggie Burger Day

Save a cow. Eat a veggie burger. That’s the message of National Veggie Burger Day, a day devoted to vegetarian variations on the burger.

And what better way to celebrate than by making your own! I’m sharing our favourite, super easy to make, veggie burger recipe with meaty umami-rich mushrooms as the star ingredient.

Why Mushroom and Quinoa?

Mushroom and quinoa are both incredibly nutritious foods. But on their own neither can replace meat. Together they provide a more balanced nutritional profile that is closer to meat.

Protein is made of amino acids, nine of which are called essential, as your body cannot produce them and needs to obtain them through your diet.

If a food contains all nine essential amino acids, it’s referred to as a complete protein.

The problem is that many plant foods are deficient in certain essential amino acids, such as lysine.

However, quinoa is an exception to this, because it contains sufficient amounts of all the essential amino acids.

Mushrooms are a rich, low-calorie source of fiber, protein, and antioxidants. And they’re packed with minerals!

For the Adults…

In winter a great wine is a nice addition to a healthy dinner like this. For this burger, I recommend the Blacksmith Wines Limbo Red.

This veggie burger and red blend are a match made in heaven. Both are juicy, crunchy, and on the lighter, fresh side.

This fruity wine has hints of strawberry, raspberry, and red cherry. The bright tannins pair nicely with the little hint of spice from the chilli flakes and the touch of sweetness from the sweet potato in the burger.

Both are utterly scrumptious and complimentary.

Happy cooking!
