Slice and dice your tri-tip while cold. Heat a skillet over medium heat and add your tri-tip, saute until warmed through. Heat your black beans and refried beans. Note: I add beer to my refried beans, a mexican beer is preferred. Prepare your rice as directed on package, while rice is cooking chop up  about 2 Tbsp. cilantro. Juice one lime and set aside. Once your rice has cooked add your cilantro and lime juice and lightly mix in with a fork. Season your rice with additional seasoning if desired. Place remaining toppings in bowls or dishes to allow for different topping selections. Be careful when rolling burrito, over stuffing may lead to a messy burrito (still delicious!).
