Preheat the oven to 375° F and lightly grease a baking sheet.
Mix together the cream cheese, cheddar cheese, garlic, cilantro, and cumin until well blended. Taste and add salt, and adjust seasonings.
Remove the stems from the jalapeños and cut in half lengthwise. Scoop out the seeds and then cut the sliced jalapeños in half, horizontally.
Place about a teaspoon of the cream cheese filling in each jalapeño quarter. Divide the sausage into 24 equal-sized portions and pat each into a 3-inch circle then place the stuffed jalapeño in the center of the sausage. Wrap the sausage around the stuffed jalapeño until it’s completely covered, and form into an egg shape.
Place sausage-wrapped jalapeños on the sheet, about an inch apart. Bake for 15-20 minutes, or until the sausage is cooked. For additional browning on top, you can place the sheet under the broiler for 2-5 minutes.
