Wash thoroughly the lentils cover them with water and boil for about 15 to 20 minutes with a bit of salt; best to follow instructions on the pack as the time depends on the type of lentil so cooking time may differ.
Peel and/or wash all the vegetables as needed. Cut/chop as you wish but preferably bigger chunks.
Place all the vegetables in a large tray so that they have some space between rather than being all stuck up if not enough space use two trays. Sprinkle some Olive oil all over the veggies, some salt and place in the oven for about 25 minutes or so. Take out, mix and turn them a little and put them back in the oven for 15 more minutes or more all depending on how cooked you want them to be if you want them crispy then leave them for a little longer. Just keep an eye on them and take them whenever you like the way they look ☺️
Sprinkle some balsamic vinegar on the lentils and the vegetables and mix together. The salad is ready to be served. Enjoy it as a side to any meat or fish or on its own.
