My lazy meal is a bit cost prohibitive if you don't have the equipment, but if you have an instant pot, a rice cooker, and an air fryer equivalent, it's super easy to make orange chicken with stir fry veggies, using all stuff you can get ready at the grocery store.
I just throw rice in the rice cooker, frozen veggies and about half a bottle of premade sauce (like $1 at Aldi) in the instant pot, and breaded chicken, like popcorn chicken, in the air fryer, then wait. Mix the chicken in with the veggies once it's cooked, and then serve over rice.
If you do non-breaded chicken, you can even cut out the air fryer, and just cook it with the veggies. Either way, you just have to set the instant pot to zero minutes at high pressure, and it'll be cooked
