In the slow cooker, whisk together beef broth, coconut aminos, coconut sugar, garlic, and sesame oil.
Place beef slices in the liquid and toss to coat.
Cover with the lid and cook on high 3-4 hours or low 5-6 hours.
Just before the last remaining 20 minutes of cooking, make a slurry with cornstarch and water in a small bowl. Pour this slurry into the crockpot, and add in the sugar snap peas.
Cook white rice according to package instructions and portion it into the side compartments of meal prep containers. Garnish with freshly chopped basil leaves.
Distribute the beef and sugar snap peas evenly among the main compartment of the meal prep containers.
