Using a food processor with the grinder attachment, grind the mushroom and eggplant together. In a large bowl, combine the mushroom mixture with the turkey, sirloin, tomato paste, oregano, basil, salt, pepper, Worcestershire sauce, paprika, red onion, garlic and egg until completely blended. Be careful not to over blend.
Spray a nonstick loaf pan once with canola oil cooking spray. Using clean hands, pat the turkey mixture into the pan.
