Prepare the peppers by cutting off the stems, then cut the peppers in half, lengthwise. Pull out the white membrane and seeds. Place the peppers on a baking sheet and bake until tender, about 10 minutes. Alternatively, you could leave the peppers raw.
Meanwhile, assemble the guacamole by mashing together (with a fork) the avocados, lime juice, cilantro, hot sauce and a good pinch of salt.
Use a small spoon to fill the peppers with guacamole. Top with bacon crumbles.
