Heat a large sauté pan or cast-iron skillet over medium-high. Add the ghee or oil, and when it is hot, add the cauliflower. Stir until the cauliflower begins to color, 1 to 2 minutes. Season with salt and pepper. Continue stirring until the cauliflower is half-cooked, about 5 minutes, lowering the heat if necessary to keep it from browning too quickly.
Step 2
Add the cumin, mustard seeds, turmeric and makrut lime leaves, if using. When they begin to sizzle, add the ginger, garlic and chilies. Stir well and add the peas, along with a sprinkle of salt. Cover to let the peas steam until tender, 2 to 4 minutes. Sprinkle with the slivered scallions and cilantro. Serve with lime wedges.
