I played several clicker games (Cookie Clicker, Clicker Heroes, Time Clicker, Tap Titans, Bitcoin Billionaire) and your idea just sounds really interesting (and intriguing, since there's human meat involved =))) ).
And the characters are so damn cute! :v I like the art style!
I don't mean to distract you from your game idea, but maybe if you find yourself stuck, you can shift the gameplay a bit from pure clicker to "click and upgrade" like AdVenture Capitalist. But in your case, instead of harvesting money from various businesses, you get money from cooking various dishes.
