Heat oven to 220C/200C fan/gas 7.
Put the carrots, potato and celeriac in
a roasting dish. Pour over half the olive
oil and some seasoning, then cook for
45-50 mins, turning occasionally, until
tender and golden.
Meanwhile, make the patties. Put the
mince, basil and fennel seeds in a bowl,
add some seasoning and shape into little
patties. Heat a griddle pan to hot, brush
the patties with oil and cook for 5-6 mins
on each side, or until cooked through.
To make the dressing, mix the
remaining oil, Parmesan, vinegar,
mustard and yogurt with some
seasoning. Lay the roasted veg and
patties over the salad, then drizzle
over the dressing and serve.
