Oats in a Smoothie?

The other day over at Kath Eats Real Food, she put raw oats into her smoothie. I was intrigued because I knew that I liked in smoothies some, whats the word, grit? roughage? I know that I like ground flax in my smoothies and occasionally I might put a couple walnuts in the blender as well, but oats? So, I thought I'd try it today. Verdict: delish!

My smoothie:
1/2 banana
2 strawberries (bought fresh, but they were on their way out, so I froze them)
1/3 cup blueberries
1 T ground flax
2 T oats
3 walnut bits
yogurt/milk
1 teaspoon whey (I know whey can be problematic as a protein source because its fairly acidic; I've tried rice protein, but its awful--though Veggie Girl claims that there is one on the market that isn't chalky, but its $42 and I'm not spending $50 with shipping in order to "try" it anytime soon. Tofu and ground hemp seeds might be good sources to use--I have the tofu in the fridge right now, but I forgot to try it this morning--one experiment at a time folks).

I used to make a smoothie for breakfast everyday for quite a while, but once I went to flex and had to be out the door by 6:20 a.m. there just wasn't time and I switched to Greek Yogurt with Granola. I think what I'll do is Monday-Thursday, do the Greek Yogurt with Granola thing at my desk and Fri-Sun, do the smoothie thing. I may take some ground flax to work to add to the yogurt as well, so that will help with the omega-3's. Sometimes on weekends, I'm tempted to make a big breakfast because I like breakfast foods, but for the near term, I really want to concentrate on max-nutrients with less calories. If I blow 500 calories on breakfast, it leaves less for the rest of the day when I'm likely to be more hungry. If I want breakfast foods, I can have an omlette or poached eggs over greens w/ toast for a lunch or dinner.

So, dear reader, let me know, what do you like in a smoothie?
