Im on the road for my pre workout meal so it eliminates alot of my food sources as i obviously dont have a microwave

i dont like fish but ive been training myself to eat it, only gag once or twice when i eat it know....lol

so for my protein i have a couple tins of tuna

but im looking for a carb source was thinking of rice crackers or bananas
I Like bananas but not sure it 50g of carbs for bananas is a good idead ?
maybe half rice crackers half bananas ?
