In a small pot, bring rice and water to a boil. Reduce heat to the lowest setting, cover with a lid, and cook for 20 minutes or until all of the water is absorbed. Remove from heat and let sit 5 minutes. Fluff rice with a fork and stir together with lime zest and juice. Set aside.
In a large saute pan, heat oil, add beef and cook until cooked through. Add taco seasoning, California Giant blackberries, and ¼ cup water. Simmer until most of the water is cooked out. Set mixture aside.
Layer ingredients in the mason jars in this order until you reach the top:
Beef and California Giant blackberry mixture
Crushed tortilla chips
Let cool and then tighten the lid. Take in a lunchbox with a cooling pack to keep fresh. When ready to eat, remove lid and microwave until warm and enjoy!
