I start by placing the vegetables (tomatoes, onion, garlic, peppers, carrot) on a baking tray. I toss them with olive oil, salt, black pepper, and smoked paprika. I bake in a preheated oven at 190°C (375°F) for 25 minutes.
In the meantime, I rinse the red lentils thoroughly and boil them in a small pot of water while the vegetables are roasting. Towards the end, I add a little salt. I drain them and set aside.
I place the roasted vegetables in the blender. I add the flaxseeds, the lentils, a little ginger, and the hot water, and blend well. My soup is ready.
To make the croutons, I simply cut the bread into cubes and toss it with olive oil and spices. I bake in the oven at 200°C (390°F) for 5–7 minutes. Halfway through, I give them a quick stir. They’re ready.
I transfer to a bowl and add some finely chopped parsley or basil and a drizzle of raw olive oil for better absorption of the vitamins.
