We in Ireland have a great rhubarb season where we’re so lucky to be able to get fresh, zingy rhubarb and use it in our favourite dishes. The sweetness of strawberries combines really well with rhubarb in this crumble and we up the nutritional value of the overall dish by adding in oats.

If you are watching your sugar intake, you can substitute the caster sugar for a sweetener of choice. I would err on the lower end of the sugar quantity as sweeteners can be more intense than regular sugar.
