In a medium skillet, heat up oil. Lower flame and sauté onions until soft. Raise flame and fry pastrami until beginning to curl, about three minutes each side.

Place avocados in a medium mixing bowl and mash coarsely. Mix in lemon juice and spices, then stir in the vegetables.

Assemble: On a flat wrap, spread a layer of guacamole. Top with a layer of pastrami and onions. Roll up tightly and slice into six pinwheels. Repeat with remaining wraps.
