How to make it

  • Preheat the grill to medium-high.
  • In a medium saute pan, saute the mushrooms in 1 tablespoon of olive oil over medium-high heat. Cook until the mushrooms begin to brown, 3-4 minutes. Stir in garlic and cook until fragrant, about 1 minute. Season with salt and pepper and remove from heat.
  • In a large bowl, combine the sirloin with 1 tablespoon oil, soy sauce, salt, pepper, mustard, herbs, and mushroom mixture. Gently mix to combine using a fork or your hands. Divide the mixture into 4 equal portions, shaping each portion into a patty.
  • Scrape the grate clean and brush with the remaining tablespoon of oil. Grill the burgers until cooked through, 3-4 minutes per side. Remove the burgers from the grill and cover to keep warm.
  • To make the spinach sauce, melt the butter in a medium saucepan over medium-low heat. Add the shallot and cook until translucent, 3-4 minutes. Stir the flour into the onions and cook 1 minute.
  • Whisk in the half-and-half, broth, salt, and nutmeg. Bring sauce to a simmer, then reduce heat and simmer for 2 minutes, until it begins to thicken.
  • Add the spinach, stirring until wilted. Mix in the cheese and lemon juice, and add more half-and-half if the sauce has thickened too much. Season to taste with salt and pepper.
  • In a skillet that has melted garlic butter, grill the bread on each side then sprinkle each side with cheese. Toast until cheese melts onto the bread and gets a little crunchy.
  • Top each slice of grilled bread with a burger and spinach sauce. Serve immediately.
