We always have fruits for breakfast so no cooking there. Every night I cook fresh and keep it very simple. One veg/meat curry. Store bought rotis/rice/idly/dosa with the curry. I make 90% Indian food and rarely make tacos, burger, pasta for my kid. Weekend I grind idly/dosa batter thats all, not much prep work needed. In 30-45 mins I finish cooking each night. I use 2-3 stoves, microwave, pressure cooker, rice cooker, magic bullet etc which aids the cooking and helps to finish fast. Also I use store bought ginger / garlic paste, store bought chopped garlic etc to save time. When I buy grocery, I clean the mint, coriander leaves, greens etc and keep them ready to cut and cook. For lunch I usually take what I make for dinner the previous night. My kid eats hot lunch provided in school.
