Preheat your oven to 350 degrees f.
Grease very lightly a round 10-inch diameter baking dish. You can use a light mist of olive oil cooking spray, or a light coating of grass-fed butter or coconut oil.
In a large bowl, combine all of your ingredients for the filling.
Transfer filling to your prepared baking dish.
Bake in the preheated oven for 15 minutes.
In a second bowl, add all of your crumb topping ingredients and stir really well to combine.
Carefully remove your baking dish from the oven and crumble this crumb topping mixture evenly over the top of your rhubarb-strawberry mixture.
Return to the oven and continue to bake at 350 degrees f for 15-20 minutes or just until nicely golden-brown and crisp on top.
Serve your hot strawberry rhubarb crisp with a dollop of frozen frozen yogurt or ice cream of your choice and enjoy!
