Dice the tuna and place in a non-reactive bowl. Add the lime juice, mescal, and chile de arbol powder, and toss to coat. Let the mixture marinate. Add the shallots, cilantro, and avocado, and gently toss to coat. Place a spoonful of the Coconut Avocado Mousse onto the center of a serving plate, then place crispy plantains on top to form a "nest" on top and spoon the ceviche into the nest. Sprinkle the radish over the plates and drizzle with the chile oil. In a food processor, combine the avocado, coconut milk, cilantro, and salt. Blend until the mixture is smooth.
