Are you talking about when the executive function is completely offline? Because if that’s hitting hard and I’m going “I’m hungry but I can’t make anything” my go to is a quesadilla.
Seriously if I can stand and heat a frying pan, it becomes easygoing to warm up some tortillas in the fry pan and throw some cheese between them. Bingo bango bongo you’ve got a Mexican cheese sandwich.
And then as I’m eating the first one I can be making a second and maybe throw in some ham or some salami, or better yet some leftover taco meat. All of a sudden I’m not so hungry and I’m happier having eaten something and maybe I can be motivated to eat some veggies or fruit.
