I'm a guy and I like to cook.
Bake a chicken the way he likes it and put it in the frig. It will keep for two to 4 days. Take the juice from the chicken, add a can of chicken broth with rice and sliced mushrooms. It makes a delightful rice pilaf. All he has to do is heat and eat. The chicken and rice compliment each other and your little one will like the flavor and texture. Or take the chicken juice from the baked chicken, add a can of chicken broth and mashed potato mix and cook. Place it in the frig beside the chicken and he can heat and eat. My little ones always like the mashed potatoes fixed this way.
Make a pot roast with carrots, potatoes, diced onions, diced celery leaves, and sliced fresh mushrooms. Take a can of cream of mushroom soup, add a can of beef broth or 2 cups of just plain water and spices. I like Canadian Steak Seasoning as well as garlic granuals (NOT garlic salt). Mix 1/2 tablespoon of flour with the broth or water before pouring it in the pot with the roast. As the roast cooks, the cream of mushroom soup and flour will mix to make a real nice gravy. He'll love the pot roast and gravy and he can use a fork to mash up the potatoes and carrots, add a little gravy and your 14 month old will love it. I use diced celery leaves, not celery stalks, because of the nice subtle flavor they give to everything.
Both things will survive in the frig over the weekend and, IF there are any left overs, you can enjoy some when you get back.
Good luck to you and yours.
