Use green or black olives in this recipe or a combination of both. Green pimento olives add a nice tang while black olives are a more mild bite. I've also made it with green on one side, black on the other to please everyone. For the Rotel tomatoes, I add one can of "regular" and one can of "mild". The rice won't be hot at all and this combo adds the best flavor. If you like it hot, change the combination accordingly.
