O.M. Peanut Butter Noodles

I'm pretty much obsessed with Thai Peanut Butter noodles lately, but a) I like my meals to be easy, and b) I've been trying to diet. So here's what I came up with.

Ingredients:
1 Block Ramen Noodles
3 TBSP PB2/PB Fit (powdered peanut butter)
2 TBSP Sesame Oil
2 TBSP Soy Sauce
1 TBSP Brown Sugar
1 TSP Minced Garlic
1 TSP Rice Wine Vinegar
1 TSP (ish) Sriracha

Directions:
1) Cook Ramen noodles (thanks for that tip, mom) according to package.
2) Throw away the Ramen seasoning packet.
3) Combine all other ingredients in a container, stir with fork.
4) Pour sauce over noodles.
5) Devour.

I had all these ingredients in my cupboard/fridge, so that part was easy for me. I'm sure there is a healthier way to do noodles, but like I said, I like simplicity. Substituting the peanut butter with PB2 cuts out over 100 calories. I tried to take the sesame oil back a bit, but the proportions didn't work, and it's a fairly heart healthy fat according to what I've read (similar to EVOO), so I just go with it now. Seriously, the step that takes the longest in all this is boiling the water for the noodles. Is this overly healthy? No. Is it a healthier version? Yes. I don't eat it every single day, but I would if I could!
