What are some good ways to express laughing in dialogue when you’re trying to suppress a laugh?

For example: “And with that, I’m done.” Lily scoffed while laughing. “To think a cheerleader could cheer me up.”

I use huffed and scoffed too much. Looking for some alternatives for “breathing out of your nose quickly to suppress a laugh-out-loud moment”.

Alternatively, how would you describe a character experiencing wonders of a new world and chuckling in excitement? I also use giggled and chuckled way too much.

“No freaking way.” He giggled as he walked around the tree.

Does that sound alright or could it be written better?
