Here's three things I like to do with my preschooler to start the day off right:
Add snipped "greens" to his eggs: Cilantro, parsely, basil, etc...whatever is green and on hand, I try to give him for the awesome, super-food phytochemicals. Added into his scrambled eggs and cheese it goes down easy.
Sweet Potatoe Pancakes: The just-add-water mix is available at Kroger. Not super cheap, but super easy and Little H eats them up!
