Recipe needed quickly please for a healthyish fruit crumble topping!

[northender]

Have decided to make a fruit crumble tonight and in view of my recent and ongoing weight loss want to try and make the topping healthier than my usual flour, butter, sugar effort, scrummy though that is!!

Lots of cornflakes? Or make your usual crumble but just eat more of the fruit and less of the topping?
Sorry, I'm useless at low fat stuff and have the rotundity to prove it.

Add some oats and nuts

oats brown sugar and nuts... divine...

Thanks all. Don't have any cornflakes so won't do that but will try oats and nuts, can't wait!
