I've been eating a lot of the above, including flax, salba, quinoa, brown rice, potatoes, kale, onions, and yes, dark chocolate (90%).
In the morning I love my smoothies: I put almond milk with either lettuce or kale, blueberries and a few cherries, salba and flax.
I have to admit, the first time I made one I was all, "It looks so healthy and yet... it tastes like complete crap!"
Luckily I just had to add more almond milk and it was fantastic. I'm addicted to them now.
I also love eggs over sauteed kale, mushrooms and shallots.
I've been eating lots of vegetable soups - potato and leek, tomato, and so on. Yummy.
I have survived very well; as long as I can have my coffee and dark chocolate I am okay. What am I saying, I am great! I couldn't do it without them; let's just call it like it is. Also I love all the nuts and seeds. And Greek yogourt is delicious.
I admit that I've had to buy some brown rice crisps, because I missed eating crunchy salty things. They're good too.
I won't do it forever, because it's not my goal. But it's been great to try out new foods and make some new healthy habits.
And once when I made my son a morning smoothie I snuck in some spinach and he didn't even know.
(If you're saying 'you go, girl' I completely agree.)
And go veggies!
