what do you guys use as an energy source?

I’m currently playing my first game of stardew and i have been a little curious about what you guys like to use for food. i’ve been making a lot of omelets but i’ve been wanting to steer away from that so i can sell more mayo and cheese. i have found some other food sources that i like but a lot of the time they require crops that are only available in a season or two. any suggestions for good energy sources?
