Heat olive oil in a skillet over medium heat. Add onion and garlic; saute until onion is softened and browned, 10 to 15 minutes. Transfer onion and garlic to a plate.
Cook pork and shrimp in the same skillet until browned, 5 to 7 minutes. Add back the onion and garlic; season with salt and pepper. Add jicama, bean sprouts, chickpeas, green beans, celery, and carrot. Cook and stir until vegetables are tender, about 5 minutes. Place filling mixture in a large bowl. Add peanuts and mix well.
Place a lettuce leaf on top of a lumpia wrapper. Place 1 tablespoon filling onto the lettuce. Roll up the wrapper, folding 1 end over the filling. Place on a serving platter. Repeat with remaining lettuce, lumpia, and filling.
