Shrimp and Orzo With a Kick

This is super quick and very yummy.  There's a little kick to it as well, but not much.  If you want more spiciness, simply leave the seeds on the jalapeno.  Enjoy!
-1 cup uncooked orzo
-12 oz shrimp, peeled, deveined, with tails removed
-5 tsp Cajun seasoning, divided
-3 Tbs extra virgin olive oil, divided
-4 Roma tomatoes,  cut into chunks
-1 small onion, chopped
-1 jalapeno, seeded and chopped (leave seeds if you want more heat)
-2 cloves garlic, minced
-1 Tbs tomato paste
-1 tsp salt
-1 tsp pepper
-1 cup shredded Parmesan cheese
Cook orzo according to packet directions.  Drain.
Meanwhile, pat the shrimp dry with paper towels.  Season with 2 tsp Cajun.  Toss well and set aside.
Toss tomatoes with 1 Tbs of the oil and 1 tsp Cajun.  Set aside.
Preheat broiler to HIGH.
Heat 1 Tbs of the oil in large skillet.  Add the seasoned shrimp and cook until done (about 2-3 minutes per side).  Remove shrimp from skillet and set aside.
Return skillet to stove and heat remaining Tbs oil.  Add the onion and jalapeno.  Cook for 3-4 minutes.  Add the garlic and tomato paste and cook for 1 minutes.  Season with remaining Cajun, salt and pepper.  Give it a good stir.  Add the tomato chunks and cooked orzo and mix well.

Sprinkle cheese on top and broil in preheated oven for 2-3 minutes or until cheese is melted and golden brown.  
Serve onto plates and enjoy!
