For a juice instead of a smoothie: If you prefer a thinner, juice-like consistency without any pulp or chunks, strain the blended smoothie through a fine-mesh sieve, nut milk bag, or cheesecloth. Press firmly to extract all the liquid. Note: this removes most of the fibre, so you'll lose some nutritional benefits, but you'll get a concentrated, easily digestible green juice.

Fresh green smoothies are best consumed immediately for maximum nutrition and the brightest flavour. However, you can store it in an airtight container in the refrigerator for up to 24 hours (shake well before drinking as separation is natural). The smoothie will darken and oxidize slightly, but it's still nutritious. You can also freeze it in ice cube trays or freezer-safe containers for up to 3 months, then thaw overnight in the fridge or blend the frozen cubes with a bit of liquid.

Meal prep tip: Pre-portion all the fruits and vegetables (except avocado and lemon) into freezer bags or containers. Keep them frozen. In the morning, just dump the frozen contents into your blender with liquid, add fresh avocado and lemon, and blend!

This green smoothie is endlessly customisable!

• Replace spinach with kale, arugula, romaine, or Swiss chard.

• Use zucchini instead of cucumber for a milder flavor.

• Try different fruits – mango, pineapple, or frozen berries for tropical vibes.

• Add fresh herbs like mint, basil, or cilantro for brightness.

• Use different healthy fats – nut butter, coconut oil, or more hemp/chia/flax seeds.

• Make it protein-rich by adding protein powder, Greek yogurt, cottage cheese, or silken tofu.

• Add superfoods like spirulina, matcha powder, or wheatgrass.

• Make it sweeter with dates, honey, or additional fruits if needed.

• Use coconut water instead of regular water for electrolytes.
