Yes, go ahead and freeze them. Put them in meal size portions so you don't waste any. I always freeze after a day or so so it will not go bad. If you have some use microwave containers to freeze then it just a matter of popping it in to reheat then eat. You can also use zip lock bags to freeze things in.
Good on you for giving these a go, look forward to seeing what you try next. In a lot of cases cooking is trial and error and we all have these with many errors.
