Roast Beef Sandwich with Walnut Romesco

"I like to toast the inside of the bread to ensure it doesn't get soggy, even with a spread on it."—Philip Pretty, Fundamental LA, Los Angeles, CaliforniaJoseph De Leo

"You usually think of roast beef with horseradish," says Fundamental LA's Philip Pretty, who created this newfangled, soon-to-be-classic combination. "But this walnut romesco has elements that bring out the beefiness, without overpowering it." Keep the romesco chunky for textural contrast.
