Add corn and browned sausage back to the veggie pan. Then add cream cheese and shredded pepper-jack cheese. Stir to combine all stuffing ingredients and adjust seasoning to taste. Set aside.
Cut slits the length of the face of each poblano. Gently remove seeds. Fill with stuffing. Top with shredded pepper-jack cheese.
