The rice is colored, and it has red kidney beans and diced carrots in it. I assume that it was cooked with some sort of sofrito. As for how authentic this stuff is, that’s questionable. It is, after all, cafeteria food. Even so, it’s at the very least inspired by Latin flavor. I think garlic, dried oregano, cumin, and vinegar is the order of the day. I’m guessing that the green peppers and leeks (or scallions) are stewed and broken down similar to what happens in sofrito.
