Cut the jalapeños in half lengthwise. Keep the stems on to prevent the cheese from spilling out, but use a small spoon or paring knife to remove seeds.
Place jalapeno halves on a baking sheet lined with foil and stuff each half with pimento cheese. Fill the pepper full, but don't overfill it or the cheese will just melt out.
Wrap each pepper half firmly with half a strip of bacon. Wrap it so the two ends are underneath the pepper so it bakes and holds.
Bake the poppers for 20 to 25 minutes until the cheese is blistered in spots and the bacon crispy on the edges.
