I suggest making a simple cheese sandwich and a fried egg sandwich and any sort of fruit those will be great ♡
Or make a protein bar that you can bake ahead and wrap to take with you.
Another quick option when you don't have something ready ahead is a piece of fruit and a handful of nuts!
1/2 cup oats
1/2 cup milk or soy milk
Tsp vanilla essence
1/2 tsp butter essence
1/2 mushed up banana
Small hand full of choc chips
