Protein and Carbo loaded lunch post workout

So I'm on day 2 of P90X Lean. I don't have the nutrition plan, so I'm just sort of winging it. I do know to eat lots of protein and that some carbs help with the energy levels.
This recipe could be really easy if you have some chicken leftover from a previous meal, or some caramelized onions (I always have some in the fridge from extras at dinner.)

Sooo here's how to make my chicken bagel with caramelized onions:

Caramelized onions:
1/2 a sweet yellow onion
1 Bay Leaf
A pinch of thyme
Pinch of s + p
Pinch of Garlic Powder
Olive Oil and a little butter for the pan (just a skinny slice of butter)

Put everything in the pan and cook over med heat until caramelized. Once you've got some onions sticking to the pan use just a teaspoon or so of balsamic vinegar to de glaze. Remove Bay leaf before eating.

Chicken:
1 Chicken Small Breast (however much you want to eat)
S+P
pinch of thyme
pinch of garlic powder
Caramelized Onion
2 tsp Balsamic vinegar
2 tsp lemon or orange juice

Season the chicken with the thyme, garlic, s+p. Top with onions, balsamic, and citrus juice. Cook in a 350 degree oven until cooked all the way through.
Once cooked, pull out of oven to cool then slice diagonally to get some big thin strips.

--Now if you want to keep this a light lunch, stop here and maybe put over a salad with oil and vinegar, or whatever you like.

To put the sandwich together:
Toast bagel ( i would recommend onion or everything) with a slice of swiss, provolone, or mozzarella (whatever your preference) over the center hole. Layer chicken and onions, spinach or romaine, and a little dijon mustard. Voila!

This meal is satisfying and full of good stuff post workout.
