Notes
Sweet potato adds moisture and helps bind the patties without changing the flavor. Cremini mushrooms provide deeper savory notes and keep the burgers tender on the grill. Pepper jack cheese brands like Tillamook or Cabot melt smoothly and complement the poblano. Use soft sturdy buns such as Dave’s Killer Bread Hamburger Buns Nature’s Own Brioche Style Buns or Ball Park Golden Buns. Char the poblano fully for a smoky tender texture that balances the jalapenos. The scallion lime mayo brings brightness and ties the grilled flavors together.
