Preheat oven to 450F. Prepare one large baking dish with cooking spray.
Season the pork with salt and pepper.
In a large bowl, toss zucchini, squash and onion with salt and pepper.
Place all the vegetables in the bottom of the baking dish in one layer. Lay the pork evenly on top. Cover the pork with hummus. Squeeze the juice of one lemon over chicken and vegetables.
Sprinkle paprika over top.
Bake for 30 minutes until the pork is cooked through (145F) and the vegetables are tender.
