Catcher dad here.
If we are playing at a tourney around us (ATL area) and are waking up at home, then a scramble bowl. 2 scrambled eggs, cheese, roasted potatoes or shredded flour tortillas, and whatever non-red protein we have cooked for the week (chicken or ham). Eats that around 5:45 so it’s well down the hatch by game time. .
If eating road food, it’s a Cfila breakfast bowl or egg white grill on any day but Sun. Sun it’s a PB&J.
No matter the food, he drinks a caffeinated V8 Fusion around 1 hr before the game, plus the expected tons of water.
