I'm glad you asked babbs this question. I can't imagine a plant based diet since I find that I can tolerate carbs, but only a limited amount. Legumes are a good source of protein but dried bean and soy I can't digest. I think without a diet heavy in meat, poultry and fish I would starve to death.

Breakfast: (All amounts are approx)smoothie with 1+cup non-fat Greek yogurt, approx ¾ cup kale (I buy organic chopped or organic whole and cut up myself and freeze for convenience.) Hand full cilantro (which I also freeze for convenience,) frozen organic mixed berries, frozen organic mango or pineapple if I can get it, splash of pomegranate juice, 2 scoops of collagen protein powder, a teaspoon each of histidine, lysine and chlorella, one capsule of vitamin C and once capsule of hesperidin (I can't swallow anything but the tiniest pills.) Some water. It makes a quart or more. Yes, it's a lot but it has to last me until 2 pm when I get back from the barn where I keep my horse. I'm out there 7 days a week. Lunch is 1 12-oz glass of non-fat milk, about 1+ cup of my homemade granola which consists of rolled oats, pumpkin seeds, sunflower seeds, and when I could eat them, walnuts. I use almond butter instead of expressed oil, and add honey and maple syrup, cinnamon (a lot,) vanilla and lemon extract. Dinner is usually steamed vegetables with rice or roasted sweet potatoes. Or I make a curried lentil soup with wilted spinach. Or I do something with tofu and vegetables. Or I make a salad with a whole avocado. My brother uses zero oil to sauté vegetables, but I use either canola oil or camellia oil to coat my carbon steel pan, wipe out any standing oil. It works like a non-stick pan. I like my mushrooms sautéed, or occasionally, I want a crispy outside to my tofu, or I sauté mirepoix for soup. This is not just a plant based diet, but also a very low fat diet. Vitamin K2, vitamin D, and of course, essential fatty acids 3 and 6 need to be supplemented because they are oil soluble. My snacks are bananas, apples or pears, and Larabars (cherry pie my favorite and no walnuts.) I did love my dark chocolate treat, but, oh well.
