Help please- Jello Salad questions

Can Jello Salad be made using packaged salad mix or even just lettuce? If so- how do I put the salad mix in without wilting the lettuce? I've never tried this before so.... Just thinking it would be something good to have during these horribly hot summer days. If it's not possible then does anyone have any alternative ideas or recipes? I don't like cottage cheese so that's out. Also don't care for anything with mayonnaise. I know, I know. I'm picky. Sorry. Thanks for all of your help.
