Cut the thinly sliced pork belly and assorted vegetables (onion, carrot, bell pepper, zucchini, etc.) into bite-sized pieces.
Heat cooking oil in a pan and stir-fry the pork belly over high heat.
When the pork is halfway cooked, add the vegetables and stir-fry together.
Season with salt, pepper, soy sauce, etc.
Serve the stir-fried ingredients over rice to make a rice bowl.
