Chris, u can always take steam fish. The night before, ask hub to season for u, with salt & ginger. Put in the chiller. Some fish like salmon, can be baked also.
Lunch, u can cook simple meals like fish, chicken/pork with mee hoon or noodles soup. Or steam, fish, chicken, prawns together, use boiling water to cook your noodle. Then stir the noodles & steamed ingredients together with XO sauce or veg oyster sauce. That makes your dry noodle with ingredents! Same, the ingredient all season the night before.
Cook some rice in morning. Hubby comes home, ask him to fry rice with ingredients, v fast one.
Give yourself a few days. U will be able to see a pattern on clariss. Some hours of the day, she will sleep longer. Use that time to do wat u need to do. I believe you can manage after CL leaves. Jia You!
