Caramelized Onion and Feta Cheese Sandwiches

I was in the mood for a gourmet but light lunch today (I have a hockey game at 1:30) so I whipped up this delicious sandwich. I used half an onion to make half a sandwich (Mr. Barefoot stole the other half). If your spouse does not hijack your meals, half an onion is sufficient for a full sized sandwich for one person. If your spouse does, use a whole onion.
Ingredients:

• 1/2 medium onion
• 2 tbs butter (actually, right now, we're using vegan margarine)
• salt
• pepper
• 1 tsp sugar
• feta cheese, to taste (would also be good with goat cheese)
• fresh rosemary (if your awesome older sister bought you a rosemary tree)
• 1 small pita
  

Recipe:

1. Melt 1 tbsp butter in skillet over medium heat. Slice onion thinly into strips.
   
2. Toss onion in melted butter and allow to saute until soft.
   
3. Add sugar, salt, pepper, and remaining butter. (May need more butter if the onions start to burn).
   
4. Continue stirring frequently for approx. 6-10 minutes, then add rosemary and saute a little more.
   
5. Add feta, stir until softened.
   
6. Spoon into pita and marvel at how such a simple sandwich could be so delicious.
   

Vegetarian Sandwiches

So last night, Mama Awesome and myself went to Solstice services. The food they served afterwards was totally fantastic, and the best part was the "caramelized onion and feta" sandwiches. It was just caramelized onion on flatbread that had been spread with feta (I did not know that you could spread feta, and it was creamier than feta, so my guess is that it was something more like laughing cow cheese.)
I have a hard time finding good vegetarian sandwiches, so I was so pleased to try something that would be easy to make and fairly portable which did not involve sprouts. I think one could easily make caramelized onions in the slow cooker and then refrigerate them for an indefinite period of time to have a constant supply for sandwich making.
