Pat chicken* dry with paper towels and season all over with half the Italian Seasoning (all for 4 servings), salt, and pepper.

Heat a drizzle of oil in a large pan over medium-high heat. Add chicken; cook until browned and cooked through, 5-7 minutes per side. Turn off heat; transfer to a cutting board. Wipe out pan.

While chicken cooks, wash and dry produce.

Trim and halve zucchini lengthwise; slice into ½-inch-thick half-moons.

Heat a drizzle of oil in pan used for chicken over medium-high heat. Add zucchini; season with salt and pepper. Cook, stirring, until softened and lightly browned, 5-7 minutes (7-10 minutes for 4 servings).

Cut broccoli into bite-size pieces if necessary. Swap in broccoli for zucchini. Cook, stirring occasionally, until browned and softened, 5-7 minutes.

Meanwhile, in a small pot, combine polenta and ⅓ cup water (⅔ cup for 4 servings) over medium heat. Mash with a potato masher until mostly smooth, 30-60 seconds (remaining lumps will be broken up when whisking).

Whisk in cream cheese, sour cream, stock concentrate, and 1 TBSP butter (2 TBSP for 4); simmer until thickened, 3-4 minutes. Taste and season with salt and pepper if desired. TIP: If polenta seems too thick, stir in a splash of water.

Slice chicken crosswise.

Divide polenta between bowls and top with chicken and zucchini. Serve.
