You could try pastas and one-pan meals - they're generally kid-friendly and easy to prepare.
One of my son's favorites is this creamy mushroom pasta which only requires ingreidents like penne pasta, butter, flour, milk, and mushrooms. It's quick and simple to make, and the creamy sauce is a plus for little ones.
Another pan meal which my family enjoys is the good ol' chicken and potatoes roast. Toss in your favorite veggies, season with some herbs and spices, and you've got a nutritious meal ready in an hour.
If you're short on time, sheet pan dinners are life savors! It's basically tossing your proteins and veggies together on a baking tray and into the oven it goes. My go-to is typically salmon with lemon slices and some seasoned asparagus or green beans.
These are just some low stress meals which I rely on for those crazy, busy nights. They're definitely not gourmet but they're kid-approved and get the job done!
