Pre heat your oven to 200C and prepare your vegetables.
Grab a large baking tray (I love my stainless steel trays, they clean up easy and are non toxic for my family), place your prepared vegetables onto the tray along with 2 Tbsp of the olive oil and 1 Tbs of balsamic. Season generously and toss to coat.
Place tray in the oven and bake for around 50 mins turning the vegetables about halfway. Let cool slightly before assembling salad.
While the vegetables are cooling a little, prepare a platter by placing your 3 cups of greens on the plate. Chop some walnuts and pull out some feta.
Pour your drained lentils onto the baking tray with the vegetables and toss to mix, then serve the vegetable medley over the greens. Sprinkle over some feta and walnuts and drizzle over the remaining Tbsp of olive oil and ACV.
Serve immediately.
