To prepare a spicy ground beef cabbage wraps with peanut sauce, you'll first need to prepare the cabbage. Cut the green cabbage in half lengthwise, and then cut each half into 4 equal-sized pieces. Place each piece of cabbage on ungreased baking sheet and cover with plastic wrap. Bake in the preheated oven for 20 to 25 minutes, or until the edges are crispy and the meat is no longer pink. Remove from the oven and let sit for 5 minutes before serving.
