In a small bowl, stir butter together with cumin and cilantro until well combined. Set aside.

To make the queso, brown breakfast sausage in a large, deep skillet over medium heat as you break it apart.

Add in butter if there isn't enough fat in the pan and saute onion with sausage until tender, about 5 minutes. Reduce heat to medium-low. Slowly melt in Velveeta. Once that is melted in and smooth, stir in Monterey jack cheese little by little, along with tomatoes and green chiles. Queso will be quite thick, so stir in the 6 oz of evaporated milk to thin slightly. Taste and adjust seasonings as needed with salt and pepper. Keep queso covered and warm, over low heat.

Bring a large pot of water to boil, about 12 cups of water. Stir in about 2 tablespoons white vinegar. Reduce heat to gentle simmer. Crack eggs individually into small bowls and pour into hot water, cooking two at a time. Cook 3 minutes and then transfer eggs to paper towels to drain. Continue cooking until all eggs are poached.

To assemble, toast English muffins and spread each half with 1 tablespoon prepared butter. Top each half with one poached egg. Pour over warm queso and top with any desired toppings. Serve immediately.
