1. Heat oven to 400°F. Combine tomatoes, oil, thyme, garlic and salt in medium bowl; toss to coat well. Arrange tomatoes, cut sides up, on metal baking sheet lined with aluminum foil. Roast in 400°F oven 30-35 min. or until skins are wrinkled and begin to brown.
2. Meanwhile, press lemon pepper evenly onto beef filets. Heat large nonstick skillet over medium heat until hot. Place filets in skillet; cook 10-14 min. for medium rare to medium doneness, turning occasionally. Remove to platter; season with salt, as desired.
3. Serve filets with tomatoes.
