In the first place of reliable meals is miso noodle soup. It's basically instant noodle but healthy. The procedure goes:
- Boil water, this is the critical path. Add egg in at the start. Water's boiled once you hear the egg clinker on the pot's bottom).
- Wash veggies (usually spinach).
- Chop up add-ins, usually ginger, veggies, tofu, ham if feeling extra fancy.
- By the time chopping is done, water's probably boiled. Spoon some out to mix with miso, add in everything. Thin noodles cook in < 5min, so its the optimal choice. If there's extra time, I'd sear the tofu and ham.
