Always eating

Ri

So our pediatrician who we adore just recommended we up baby's food to 3 meal (we've been doing this for a while) and 2 snacks a day (this is new) plus his 10 oz of breastmilk and 15 oz of formula. I feel like all I am doing is cooking and dishes lol. Anyone else in the same boat and what are easy things you have readymade? I plan each day's meals ahead the night before to make it simpler and make things like veggie pancakes, Turkey veg. Meatballs, and hard boiled eggs, steamed veggies, and fresh fruit cut up just to make things easier. I am finding he is just a tank and will eat us out of house and home. He eats everything but avocado (allergies). Open to suggestions. He has 8+ teeth and is in the 92 percentile so we like to give him well balanced meals for his major growth in height and keep weight on him.
