It depends on the kind of workout. If its got a strength component I like a hardboiled egg plus some little bit of carb (1/2 slice of toast.) But these days, I'm liking my hot lemony/pepper drink with a tsp. of honey. 1 cup of warm water, 2 tbsp. of lemon juice, 1 tsp. honey. I nuke the water for 2 min. in the microwave and its just right. It really hits the spot and helps with indigestion. I don't know why it works, I saw it online and tried it thinking this will never work. I don't think its helped me lose any weight, but its very satisfying and I just don't feel hungry for about two hours.
For me, I have had a difficult time with eating before a workout, I often have it come up on me. I did best with 1/2 a granola bar (you can make your own with organic oat meal.) I hope that helps.
The other option is a protein shake, I like the one I get at the co-op (probably like one you can get locally) its made with Stevia, organic whey protein, pure coco powder. I have a shaker bottle that I mix it with milk. But you could get one that is not dairy, not everyone can do the dairy. A lot of my vegan friends swear by pea protein, I just don't do well with it. The protein shake goes down easy, hardly any digesting to do, and in about 20 - 30 min. I can exercise. It takes me a minute to get dressed and my lunch ready for work anyway.
