75 minute or under recipes ideas

Hello! :) I'm looking for ideas for a foods class project.

I'm limited to a 75-minute class period, so I was hoping you all would have some ideas for shorter recipes. Preferably, nothing with parts that I have to prep ahead of time by anything more than mabye a half hour would be great.

I'm not limited ingredients-wise, other than no alcohol or peanuts.

Thanks so much in advance for the help!
