It seems like there might be a typo in the name of the food you're asking about. I'm assuming you're referring to "Chiles Rellenos" which is a popular Mexican dish that can be found in many restaurants in the USA.

Chiles Rellenos are large, mild green chili peppers that are stuffed with a variety of ingredients, typically including cheese, picadillo (a mixture of ground meat, onions, and seasonings), or beans. The stuffed peppers are then dipped in a batter and deep-fried until golden brown. They are usually served with a tomato-based sauce and can be garnished with ingredients such as sour cream, avocado, or fresh cilantro.

Chiles Rellenos can be a delicious and flavorful dish, but they can also be quite spicy, depending on the type of pepper used. If you're sensitive to spicy food, you may want to ask your server if the peppers are mild or if they can adjust the level of spice for you.
