• Bring a medium pot of salted water to a boil. Wash and dry produce. • Trim and quarter mushrooms (skip if your mushrooms are pre-sliced!). Trim and thinly slice scallions, separating whites from greens. Dice tomato. **Rinse shrimp under cold water. Pat shrimp or chicken dry with paper towels; season all over with salt and pepper. Heat a large drizzle of oil in a large pan over medium-high heat. Add shrimp or chicken; cook, stirring occasionally, until cooked through, 4-6 minutes. Turn off heat; transfer to a plate and cover to keep warm. Wipe out pan.**

• Melt 1 TBSP butter (2 TBSP for 4 servings) in a large pan over medium-high heat. Add panko; cook, stirring, until golden and toasted, 2-3 minutes. • Stir in half the garlic powder (you’ll use the rest later). Cook until just fragrant, 30 seconds. Season with salt and pepper. Turn off heat; transfer to a small bowl. Wipe out pan. **Use pan used for shrimp or chicken here.**

• Add penne to pot of boiling water. Cook, stirring occasionally, until al dente, 9-11 minutes. Drain.

• While pasta cooks, heat a large drizzle of olive oil in same pan over medium-high heat. Stir in mushrooms and a pinch of salt. Cook, stirring occasionally, until browned and tender, 5-7 minutes. Reduce heat to medium.

• Stir scallion whites, remaining garlic powder, and 1 TBSP butter (2 TBSP for 4 servings) into pan with mushrooms. Cook, stirring, until fragrant, 30 seconds. • Stir in stock concentrate, cream cheese, half the Parmesan (save the rest for serving), and 1/3 cup water (½ cup for 4). Cook, stirring, until combined and creamy, 2-3 minutes. Turn off heat. • Stir in tomato, another 1 TBSP butter (2 TBSP for 4), and truffle seasoning to taste. Season with salt and pepper. **Stir in shrimp or chicken along with tomato.**

• Stir drained penne into pan with sauce until thoroughly coated, adding water a splash at a time until sauce reaches a creamy consistency. • Divide between bowls; top with scallion greens and remaining Parmesan. Sprinkle with as much garlicky panko as you like and serve. ***Chicken is fully cooked when internal temperature reaches 165°.***
