Crockpot Jambalaya

I made this tonight and it was a huge hit. I tend to find crockpot dishes bland and disappointing but this one was perfect.

1 pound smoked sausage, sliced into 1/2″ rounds
1 pound boneless, skinless chicken thighs, cut into 1″ chunks
1 pound raw shrimp, peeled, deviened (I use 26/30 count)
1 28 oz can crushed tomatoes
2 cups chicken stock (or one 15 oz. can)
2 yellow onions, diced
2 celery ribs, diced
1 jalapenoe, seeded and deviened, minced
4-6 garlic cloves, minced
2 bay leaves
.5 tsp dried thyme
.5 tsp cayenne
2 tsp kosher salt

Dump everything except shrimp in crockpot and stir. Cook on high for a 3-4 hours, adjust seasonings, then reduce heat to low. Stir in shrimp and cook until shrimp is opaque, 15-30 minutes. Serve over rice.
