Drop in your mixed veggies, hard vegetables first and bring to a boil. Add the leafy veggies last as it cooks quickly. The traditional "Nilaga" vegetables include potatoes, cabbage, napa cabbage, pechay or bokchoy, carrots and green beans. I suppose u can try spinach too. Taste and season if needed. (unpeeled but brushed potatoes, it's my thing, LOL, not very cheffy but I want the nutrients in it).
