Japchae (Korean Glass Noodle Stir Fry)

Used a handful of sweet potato noodles, 1.5 red capsicum, 2 medium carrots, 1 bunch spinach, 1 brown onion, 4 cloves garlic and 1 pack frozen beef hotpot slices (recommend using less fatty meat next time). Added 1 Tbsp sesame oil near the end of cooking before dishing up.
