Peel and finely chop the onion. Peel and mince the garlic. Roughly chop the spinach. Heat the first measure of oil in a medium-deep frypan over medium-high heat. Cook the onion and half of the garlic, stirring, for 3 mins or until softened. Add the lentils, tomatoes, Italian herbs, tomato paste, honey, and 60ml of water to the mixture. Reduce the heat to medium and cook, covered, for 10 mins to develop the flavour. When there are 2 mins of cooking time remaining, stir in the spinach.
