The X Rice

I'm glad to hear that you're interested in learning about different types of food! The "X" rice you're referring to is likely either Mexican-style or Tex-Mex-style restaurant rice. This type of rice is a popular side dish in many Mexican and American Mexican restaurants in the United States.

The rice is typically made by sautéing long-grain white rice in oil or lard until it becomes lightly toasted. Then, chicken broth or water, tomato sauce or diced tomatoes, and spices such as cumin, garlic, and onion powder are added. The mixture is then brought to a boil, covered, and simmered until the rice is fully cooked and the liquid has been absorbed.

The rice is often seasoned with salt, as well as other spices such as chili powder or oregano, to give it a distinct flavor. Some variations of this rice may also include ingredients such as diced vegetables, such as carrots or peas, or proteins such as shrimp or chicken.

This type of rice is often served as a side dish with Mexican-style entrees such as tacos, burritos, or enchiladas. It's also a common component of combination platters, which often include a variety of different dishes.

It's a delicious and versatile dish that can be easily made at home and can be a great addition to any meal.

I hope this helps you understand more about the "X" rice you have found in restaurants in the USA. Let me know if you have any other questions.
