Recipe
1. Preheat oven to 375 ° F. Spray an 8 x 4-inch loaf pan with vegetable cooking spray. Set aside.
2. In a large nonstick skillet, heat oil over medium-high heat. Add vegetables, garlic, and thyme. Cook, stirring until vegetables begin to soften, about 5 minutes. Transfer to a plate; cool slightly.
3. In a large bowl, combine the egg whites, bread crumbs, ketchup and salt. Add turkey and beef; mix until just blended. Add vegetable mixture; mix well.
4. Press into prepared pan. Bake until a skewer inserted in center feels warm, about 55 minutes. Let stand for 10 minutes. Cut into slices and serve.
