It’s too late to comment on the new Australian Guide to Healthy Eating but you may like to take a peek. Every decade or so a panel of experts review and update what becomes the foundation of nutrition policy in schools, nursing homes, institutions and healthy eating campaigns.
Healthy vegetarian eating is not “meat and veg without the veg.” Forget the low carb diet too as the proteins in grain foods are critical to complete the plant based protein sources. Plus….you gotta eat legumes every day (lentils, tofu, chickpeas, homus, falafel, baked beans, 3 bean mix etc..). Toss out the refined carbs too as they wont give you enough nutrients. Choose grainy breads and cereals.
I would swap the ratio of oil to vinegar in this recipe: 2 tbls vinegar, 1 tbls oil just to make it lighter but still tasty. Leaves a few more calories for the nuts. http://woolworths.com.au/wps/wcm/connect/Website/Woolworths/FreshFoodIdeas/Recipes/Recipes-Content/Roast-sweet-potato-and-macadamia-nut-salad
