In a blender, combine all of the remaining ingredients and blend until smooth and creamy. Pour the sauce into the pot in which the pasta was cooked and cook stirring, over medium-high heat, until the sauce is hot, bubbly, and thickened, about 4 minutes. Add the pasta and vegetables to the sauce, stirring gently to combine and heat through. Transfer to a casserole dish and sprinkle with the reserved panko. Serve hot.
