I workout early in the morning. Unless my stomach is grumbling when I wake up, I eat nothing before riding. If it is then I’ll have a banana, raisins, or craisins - basically fruit that gets my stomach to quiet down.
On the bike I fuel with a DIY mix in my bottle of about 90-110 grams of carbs. It usually lasts a two-hour workout plus another bottle of just water. I occasionally also take a gel (or two) if I’m struggling or if it is a very intense workout.
Then I have a coffee on my drive to work and eat breakfast in the office.
