Slice rhubarb into 3” pieces. Add to your baking dish and toss with sugar, vanilla, cardamom, zest and juice.
Bake for 20-25 mins or until rhubarb is just tender. This is good served warm or cold, but be sure to let it cool for at least 10 mins and ’cause that liquid is boiling hot.
Add a generous scoop of yogurt to your plate, top with rhubarb, some of the braising liquid and sprinkle with toasted, chopped pistachios. Eat up!
