5. Colorado Lamb Burger
At Rioja in Denver, chef Jasinski sources local lamb for several signature entrees. The Rioja burger repurposes lamb scraps from other cuts, making for a cost-effective and waste-reducing menu item. For the buns, the kitchen proofs 4-ounce balls of pizza dough, flattens the balls slightly, sprinkles them with olive oil and Parmesan cheese and bakes them at 550 F until toasted. If pizza dough is unavailable, substitute potato buns.
