Boil 1 cup of water (add salt if wanted). Add 1 cup of rice, cover, remove from heat.
Pour corn into microwaveable bowl, heat for approximately. 1 minute, stir, heat for approximately 30 seconds more. Do the same for the kidney beans. Mix 1/2 cup of beans and corn together in bowl. (The rest of the corn and kidney beans can be put in the refrigerator to be eaten later. Once all water has absorbed from rice, add beans and corn. Add teaspoon of cajun powder and mix well. Salt to taste.
Warm tomato sauce in microwave for approximately 1 minute or until hot. Mix with the rest of the ingredients well. Enjoy.
All ingredients are approximate measurements as I just added as I went on. Add more or less to suit your taste. This served 1-2 people. Add more ingredients for more people.
