- Preheat a large skillet over medium-high heat and add in 1/2 cup of lard. When the lard begins to sizzle, add in the diced pork and sauté it until lightly browned on all sides, about 5 minutes. 
- Add garlic, onion, mustard powder, sage, pepper and cumin. Sauté for another 3-4 minutes or until the onions are softened and lightly browned. 
- Sprinkle the flour over the top of the mixture and stir for 2 minutes to create a roux. Then stir in the tomato paste and oregano until evenly combined before adding in the jalapeños, green chilies and diced tomatoes. 
- Add in the water and chicken broth and stir to combine. Bring the mixture to a boil, then reduce heat to low, cover the pot and simmer for 30 minutes. 
- Once cooked, season to taste with salt and pepper before serving over grilled meats or other dishes.
