Blend peppers, mayonnaise and basil leaves in food processor until smooth and creamy. Season with salt and pepper; cover and refrigerate. Using kitchen twine, tie the beef before cooking to hold its shape. (Season with salt and pepper if not using peppercorn seasoned beef.) Heat 1-2 tablespoons olive oil in heavy skillet over medium heat. Add beef and cook until browned on all sides and cooked to desired doneness; approximately 10 minutes for rare. Let rest for 15 minutes; Remove string, slice into thin slices or freeze beef for 2-3 hours for easier slicing. Spread bell pepper mayonnaise on each crostini and top with thin slice of beef.
