Over baked my Moong Dal Namkeen

I tried making Moong Dal namkeen at home with my oven The oven is super new and this is the first time I’m using it I accidentally over baked it It’s now too hard to chew I don’t want to waste it Is there a way I can salvage it and if not at least a way to use it elsewhere? Can I grind it into a powder and use it for something maybe? Please let me know Thank you
