well I think a big mistakle ppl make is identifying certain foods with certain times of day just becuase its breakfast doesnt mean it needs to be so called breafast foods just get good foods. Hell crack a few cans of tune, a peice of fruit and nuts. Just eat. Its just another meal a feeding.
You can have so called breakfast foods at night.
Just get things that don’t require refrigeration.
Nuts like Almonds
Energy Bars / Wholesome breakfast bars
Fruits - Apples, Bananas, etc.
Just get a box of things like that and you’re good to go.
Don’t forget to drink plenty of water
