Best treat for a puzzle toy

[RPB]

I just brought this puzzle toy for my cat and wanted to know what a good treat to put in would be. I feed her wet food and as for treats I give her temptations but I wanted to get away from temptations and give her something healthier. I’ve tied freeze dried chicken but she wasn’t into it. Any ideas on what treat I can put in the puzzle?

I just put a little good quality dry food in them. Much fewer calories and fat. There are some that have no by-products and are all meat.
