Place a skillet over medium high heat and add olive oil to the pan.  Once heated, add in bell peppers and onions.  Let cook, stirring occasionally for about 5-7 minutes or until soft and slightly browned.  Add a pinch of salt and set aside.

In a medium bowl combine Safe Catch Tuna, chili powder, cumin, lime, salt and mayo and stir to combine.
