In a cast-iron skillet, on medium-low, heat the coconut oil.
Add pecans and toast them until golden brown (~ 5-6 minutes). Let cool, then coarsely chop.
Combine almond milk, rice, sugar, salt, and 4 cups water in a large saucepan; scrape in vanilla seeds and add pod.
Bring to a boil, reduce heat, and simmer, stirring occasionally, until rice is very tender and mixture resembles loose rice pudding or oatmeal, 60-70 minutes.
Remove the vanilla pod.
Serve the porridge topped with strawberry rhubarb puree (or jam) and toasted pecans.
