This chicken and rice casserole would be yummy enough with just the salsa, Cheddar and sour cream. The bounty of sauteed mushrooms is an oh-so-good bonus.
Coca is a crust or pastry that may have a sweet or savory topping. This savory coca is an everyday Catalonian dish and would make a tasty main course dish. We used leftover Samfaina topped with ricotta cheese (which is very similar to the fresh cheeses you would find in Catalonia) and sprinkled with kosher salt. You could also top it with greens, pine nuts, and paprika.
