To the pan add tomatoes, celery, onion and poblano cooking for 3-5 minutes. Cook just until softened and tomatoes have wilted.
Add broth, orzo, Cajun seasoning and salt, adjusting both to taste. Mix well.
Bring to a boil then immediately lower to a simmer, covering with a lid leaving it slightly offset. Simmer for around 15 minutes just until orzo has softened and absorbed liquid. Stir in monterey jack cheese and cream, mix well. (If needed, you can add more cream or broth to thin.)
Preheat oven to broil. In a small bowl, toss together panko and Parmesan cheese with melted butter. Sprinkle on top. Place under the broiler for a few minutes, just until browned.
Serve immediately as an entree or a side dish.
