Arrange the beetroot slices on
a platter. Cut the mangoes either
side of the flat stones, then peel and
thinly slice the flesh. Lay the slices
over the beetroot. Roughly crumble
the goat’s cheese on top, then
scatter over the rocket.
Mix the orange and lemon juice,
mustard and some seasoning in a
small bowl. Whisk in the oil, then
drizzle over the salad.
