A homemade pesto made from arugula and almonds provide delicious flavor as the marinade for Top Round Steaks. Round out the dish with tomato and onion sauce.
To prepare pesto, place arugula, almonds, garlic, lemon juice and lemon peel in food processor container. Cover; process until finely chopped. With motor running, slowly add oil through opening in cover, processing until smooth. Season with salt and pepper, as desired. Remove and reserve 1/4 cup pesto for serving; cover and refrigerate. Place beef steak and remaining pesto in food-safe plastic bag; turn steak to coat. Close bag securely and marinate in refrigerator 6 hours or as long as overnight, turning occasionally.
Heat 1 tablespoon oil in large nonstick skillet over medium heat. Add onion; cook and stir 4 to 5 minutes or until tender. Add tomatoes; cook 8 to 10 minutes or until most of liquid has evaporated, stirring occasionally. Stir in vodka; cook 7 to 10 minutes or until thickened, stirring frequently. Season with salt and pepper, as desired. Cool to room temperature.
Remove steak from marinade; discard marinade. Place steak on grid over medium, ash-covered coals. Grill, covered, 10 to 11 minutes (over medium heat on preheated gas grill, times remain the same) for medium rare (145°F) doneness, turning occasionally. (Do not overcook.)
Carve steak into thin slices. Serve over vodka-tomato sauce; Top with reserved Arugula Pesto. Garnish with cheese, if desired.
