Mums, how do you eat properly when you don't have 5 minutes?

I'm breastfeeding and I'm supposed to be eating more than usual. In reality I eat Aarav's leftover paratha standing at the kitchen counter and call it lunch. By the time the baby sleeps and Aarav is at playschool, I have 40 minutes and I choose sleep every time. I'm not even asking for healthy. I'm asking for actual meals. What do you keep in the fridge that you can eat with one hand? My mother-in-law's answer is "have some laddoos" and I've had enough laddoos for one lifetime.
