Can I use olive oil to roast veggies? Or do I need to stick to steaming?

You can use a variety of cooking methods. There's no need to stick to steaming. Baking/roasting is an excellent and fuss free cooking method. Just pop it in the oven and wait for the dish to be done. Do try to stick to extra virgin olive oil for your baby's food though as heat is is not used in the process of deriving extra virgin olive oil and it has not undergone any chemical process. http://canigivemybaby.com/olive-oil/ http://wholesomebabyfood.momtastic.com/cookingbabyfood.htm http://wholesomebabyfood.momtastic.com/cookingbabyfood.htm
