Why I love meatless burgers so much

Currently I am enjoying veggie burgers like these gluten-free black bean burgers so much more than their meaty counterparts.

There’s just endless variation in terms of what you can put into a veggie patty: healthy grains, legumes, herbs, actual veggies! Hello! It will never get boring!

For me personally, they’re waaaaay more satisfying than a beef or chicken patty.  I am always amazed by the complex flavor profile that can be achieved with a veggie burger and they’re packed with a wider array of nutrients in addition to protein.

Homemade Mayonnaise with Hatch Chile!

Hatch chiles are in the height of their season like right meow, and they’re practically overflowing in the produce bins of all my local grocery stores. I figured I’d help them out with their surplus issue and share a recipe featuring hatch chiles.

If you’ve never had a hatch chile you seriously need to run out to the store and buy some immediately. I’m sure you won’t have any trouble finding them.

Is Hatch Chile spicy?

Hatch chiles have a subtle kick to them for sure, but also this insane grassy, bitter, green flavor that is especially enhanced when they’re roasted and charred.

Tips for making the best vegan black bean burgers:

  • This recipe works best with leftover day-old quinoa.
  • I recommend you use shiitake mushrooms as they have way more umami than any other mushroom. If you cannot find shiitake, use portobello.
  • I used old-fashioned rolled oats in this recipe for more texture.
