Grab a large pot. On medium heat, melt the butter in the pot. Add canola oil. Sauté onion and half of the chopped peppers for 2-3 minutes.
Add rice. Sauté for another 1-2 minutes.
Add cola and water. Then add salt to taste. Once you do that, raise heat to high and bring everything to a boil.
Once it’s boiling, cover pot and reduce heat to medium low. Let it simmer for another 10-15 minutes. When the rice is cooked, remove the pot from heat.
Mix in walnuts, raisins and ham. Garnish with remaining chopped peppers and enjoy!
