• Bring a large pot of salted water to a boil. Wash and dry produce. • Trim and quarter zucchini lengthwise; cut crosswise into 1⁄2-inch-thick pieces. Trim and thinly slice mushrooms (skip if your mushrooms are pre-sliced!). Halve tomatoes. Mince chives. Quarter lemon.

• Heat a drizzle of olive oil in a large pan over medium-high heat. Add zucchini; season with salt and pepper. Cook, stirring occasionally, until golden brown and softened, 4-6 minutes. • Turn off heat; transfer to a medium bowl. Wipe out pan.

• Heat a drizzle of olive oil in pan used for zucchini over medium-high heat. Add mushrooms and cook, stirring occasionally, until golden brown and slightly crispy, 5-7 minutes. • Turn off heat; season with salt and pepper. Transfer to bowl with zucchini. Wash out pan.

• Once water is boiling, add penne to pot. Cook, stirring occasionally, until al dente, 9-11 minutes. • Reserve 1 cup pasta cooking water, then drain.

• While penne cooks, heat 1⁄2 TBSP butter (1 TBSP for 4 servings) and a drizzle of olive oil in pan used for mushrooms over medium-high heat. Add tomatoes and season with 1 tsp Italian Seasoning (2 tsp for 4), salt, and pepper. (Use the rest of the Italian Seasoning as you like.) Cook, stirring, until tomatoes are softened, 2-4 minutes. • Stir in half the chives and juice from half the lemon. • Reduce heat to low, then stir in stock concentrate and 1⁄4 cup reserved pasta cooking water (1/3 cup for 4). • Whisk in crème fraîche; season with salt and pepper.

• Add zucchini, mushrooms, and drained penne to pan with sauce; stir to combine. Stir in 1 TBSP butter (2 TBSP for 4 servings) until melted. TIP: If needed, stir in more pasta cooking water a splash at a time until pasta is coated in a creamy sauce. • Divide pasta between bowls. Sprinkle with Parmesan and remaining chives. Serve with remaining lemon wedges on the side.
