For the meatloaf, mix all ingredients in a bowl and transfer to a greased and parchment-lined loaf tin. Bake at 350°F for 45 minutes or until cooked through.
For the mashed cauliflower, steam half a head of cauliflower for 20 minutes or until tender. Add to a food processor with the butter and parmesan cheese. Pulse until smooth, adding a splash of water if necessary.
For the zucchini, cut the zucchini squash into spears and roast at 350°F for 10 minutes. Add the garlic, oil and turmeric to a bowl.
Remove the zucchini from the oven and cover in the oil mix. Return to the oven for 20 minutes or until cooked through.
