Separately chop onion and garlic into small pieces. Cut bell peppers into 1 cm cubes.
Heat the pot on a bit higher than medium heat, add olive oil and add chopped onions. Cook it till the onion starts to become brown and add garlic. Cook for 1 min.
Add beef and with a spatula break the beef into small pieces. When most of the beef changes color add all the spices. Cook for a couple more minutes and try if the taste of beef is good for you. Add more spices if needed.
In the mixture put bell pepper, stir and cook for a minute.
Add tomato paste and chicken stock, mix for a minute till tomato paste dissolves. Add corn, beans, rice and mix it well.
Lower the heat to lower than medium and cook for 10min.
After 10min check if there is enough spices for you and add more if you like. Cook for 10 more minutes.
While everything is cooking, chop the green onions. After 10 minutes, check if rice is done and if so add cheese and green onions (if no, cook a bit longer till rice are done). Mix and cook for one more minute.
Serve with tortilla chips and cheese on top.
