Combine the oil, broccoli and garlic in a large bowl and toss well.
Heat a large frying pan over medium-high heat and add the broccoli-garlic-oil mixture. Keep stirring the broccoli and garlic frequently so that they do not burn.
Add a few splashes of water to the pan if the ingredients start to stick.
Continue to stir until the broccoli is just soft and the garlic is lightly golden.
In a large serving bowl, combine the broccoli mixture with the chickpeas, beans, lettuce, spinach, parsley, lemon zest and juice.
Toss well to combine all the ingredients and add sea salt and pepper to taste.
