Smoothies

I've recently wanted to start making smoothies and stuff in my nutribullet that has just been sitting around. I made one today with what I had at home, but I really want to go to the store to get more things. I was wondering if any of you had recipes that you really like for smoothies? I think it will be really beneficial for me. Especially since I can disguise veggies in them as well. I am almost 9 weeks pregnant with twins, and always hungry. I figured this would be a healthier alternative to snacking in between meals. And will probably help with the digestive issues too haha any recipes or tips are greatly appreciated!
