1) Preheat grill to medium-high heat and lightly oil the grates to prevent sticking.
2) In a food processor, pulse together cream cheese, goat cheese, sun-dried tomatoes, basil, salt and pepper. Cut the roast into round slices between 1/8-inch thick. If they are a bit too thick you can pound them out a little between 2-sheets of plastic wrap with a flat sided meat mallet. Season the beef with salt and pepper.
3) Spoon about 2 teaspoons of the cream cheese mixture onto the center of each slice of beef. Fold the meat around the cream cheese mixture to form a ball, trying not to overlap the beef too much in 1 spot. Place the ball, seam side down onto a slice of pancetta and wrap it around the beef ball. Secure the pancetta in place with water-soaked toothpicks.
4) Grill, turning occasionally, until the pancetta is crisp, about 2 minutes per side.
