Chilis are little plants that grow spicy things that make our food taste special. They come in lots of different colors and shapes, like green, red, yellow and orange. When we eat them, our mouth feels like it's on fire a little bit. But don't worry, it's not really on fire, it just feels that way because of a chemical called capsaicin that's inside the chili. Some people love chilis and think they taste delicious, while others don't like them because they're too hot. But whether you like them or not, chilis make our food more interesting and fun to eat!
