For quick pickled red onions: Pour vinegar, water, sugar, salt, and spices into a small saucepan, stir and simmer over medium-low heat.
Once sugar and salt dissolve, remove from heat and pour mixture over sliced red onions. Set aside and allow mixture to steep for at least 30 minutes.
Place a skillet over medium heat and add oil. Add cubed pork and sauté for 7 to 8 minutes or until pork pieces have just cooked through. Remove from heat and transfer to a bowl.
To assemble: Scoop hummus into each bowl and top with shredded cabbage, cucumber, pork, some pickled red onion, crumbled feta, and cilantro. Serve.
