To make a veggie version of
these jackets, swap the tuna for
some crumbled feta.
Scrub the sweet potatoes and prick all
over with a fork. Place on a microwaveable
plate and cook on High for 18-20 mins, or
until tender. Split in half and place each
one, cut-side up, on a serving plate.
Flake the drained tuna with a fork
and divide between the sweet potatoes.
Top with the red onion and chilli, then
squeeze over the lime juice. Top with
a dollop of yogurt and scatter over the
coriander, to serve.
