Grilled Beef Tenderloin Sandwiches

My daughter shared these hearty sandwiches with me, and I think they're a savory melt-in-your-mouth treat. The sweet-sour onions and mushrooms are perfect over the tender beef and lip-smacking garlic mayonnaise. —Ruth Lee of Troy, Ontario

  • 1 whole garlic bulb
  • 1/2 teaspoon canola oil
  • 1/4 cup fat-free mayonnaise
  • 1/4 cup plain yogurt

  • 1-1/2 teaspoons sugar

Directions

  • Combine the first 4 ingredients; rub over meat. Refrigerate for 2 hours. Remove papery outer skin from garlic (do not peel or separate cloves). Cut top off of garlic. Brush with oil.

  • In a large nonstick skillet, heat olive oil and saute onion for 5 minutes. Reduce heat; cook and stir for 10-12 minutes or until onion is golden. Add mushrooms; cook and stir until tender. Add next 4 ingredients; cook until reduced slightly
  • Lightly oil the grill rack. Grill beef, covered, over medium heat or broil 4 in. from the heat for 5-6 minutes on each side or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°). Let stand for 10 minutes before cutting into 4 slices.
  • Serve warm on bread with garlic mayonnaise, arugula and onion mixture.
