Clare,
From someone who grew up on meat and potatos and many veggies, I can say i feel your pain. One thing i know as the more you eat them and cut out the other foods your body will start to crave the veggies. You will develop a taste for them. The hard part is the beginning. My wife and I started doing smooties in the morings. Strawberries, kale, banana, mango along with almond milk. I hated kale in the beginning. Now i eat kale chips like candy when i need a pick me up. I also stated by grilling my veggies like peppers and onions the sweetness of the onions and peppers made it easier to eat. I can say we grill all year round and do kabobs at least once a week even when it is below freezing. It took a while but it can happen.
