Mac N Cheese w/Little Smokies was a kid favorite here.
Carrots N Ranch dip - I've not seen too many kids who won't eat this.
Beannies N Weannies - another easy fast one. Cut up hot dogs & Ranch style beans. Add cumin for decent flavor.
It's the 'N' that does it!
You'll do fine. Choices are fine - "we've got cereal or yogurt, which would you like?"
"We've got spaghetti or frozen pizza, which would you like?"
"We've got scrambled eggs or cinnamon toast, which would you like?"
I'm with Princess Perky, if they learn you aren't always gonna cave and go drive thru or order in, then they'll learn to pick from what you have available.
