To cook the collards:
Bring a large stockpot of water to a full boil
While water is heating, cut the hard stem out of the center of the collard, I go about half way up the leaf. You can shave any excess stalk off of the remaining center stem, if necessary
Add collard leaves, one at a time to pot and boil for 2-3 minutes
Drain leaves and rinse with cold water, pat dry and set aside
For the rice:
Heat olive oil in a sauce pan over medium heat
Saute onion for 3-4 minutes, until beginning to soften
Stir in garlic and cook a few more seconds, stirring constantly
Add stock, water and tomato paste
Whisk until tomato paste is dissolved
Add rice and bring to a boil over high heat
Reduce heat to low, cover, and simmer for 20-25 minutes or until liquid is absorbed. *Note: the liquid should be absorbed but the rice will still be slightly undercooked- this is what you want because it will continue to cook in the slow cooker and won't turn to mush.
To make the sauce:
Whisk together the tomato sauce, lemon juice, coconut sugar and Worcestershire sauce in a medium bowl
Season with salt and pepper, to taste
To assemble the rolls:
Place collard leaf on a flat surface
Top with 2-2.5 oz thinly sliced sirloin tip steak and 1/4 cup rice mixture
Fold bottom pieces up, then fold in sides and roll-up to seal
Place 1/4 cup sauce mixture into the bottom of the slow cooker
Add in rolls and pour remaining sauce over top
Cook for 4 hours on low. Enjoy with your favorite hot sauce. We love them topped with sweet and spicy Tiger sauce!
