Start by preparing the dumpling filling. Brown the beef and add diced onion, minced garlic, salt, pepper, red pepper flakes, coriander, and cumin. Set aside.
Next, prepare the tomato sauce. Pour in tomato puree, turmeric, salt, red pepper flakes, and pre-boiled yellow split peas.
Let the sauce simmer. Now, it's time to work on the dumplings. Wet the edges of the Mantu wraps and place a portion of the filling in each.
Fold the wrappers so that opposite corners meet, and press them firmly together.
To steam the dumplings, oil the bottom of your steamer and steam for at least 15 minutes.
While they are steaming, prepare your Chakkah (yogurt sauce). Mix together plain Greek yogurt, minced garlic, and salt. Adjust the consistency by adding water until desired thickness is reached.
Finally, it's time to plate your Mantu. Add a layer of Chakkah, then the steamed dumplings, then another layer of Chakkah, followed by the tomato sauce. Finish it off with dried mint and chopped cilantro.
