Toss together the chicken, rice (don't cook it yet), sour cream, creamy chicken soup, frozen onion and pepper blend, diced tomatoes (with their juice!), chicken broth, fajita seasoning, plus half of your cheese blend in a big bowl. Stir well so it all comes together nicely.

Pour that mixture into your greased pan and spread it out with a spatula so it's even all over.

Put foil on top and stick the pan into an oven preheated to 175°C. Let it bake for 35 minutes.

Take the foil off, cover everything with the rest of your cheese, then bake it again without the foil for another 10 minutes. Wait for the cheese to get bubbly and browned in spots.
