Vegan Whole30 Cucumber Avocado Cups
Cool, crisp cucumber rounds filled with creamy, lime-bright avocado — this appetizer is the kind of thing that disappears from the platter before you even finish setting it down. Every single ingredient here is whole, plant-based, and completely unprocessed, so it checks every box without any substitutions or workarounds needed. The filling comes together with ripe avocado, fresh lime juice, red onion, cilantro, and a touch of cumin, giving you layers of flavor that feel far more impressive than the effort involved. A little jalapeño and red pepper flakes let you dial the heat up or down depending on your crowd. Because the cucumber acts as the vessel, there's no bread, cracker, or wrapper to fuss over — just clean, vibrant bites that are naturally gluten-free and entirely animal-product-free. These are ideal for warm-weather gatherings, meal-prep snacking, or any time you want something that looks elegant but takes almost no time to pull off. Serve them immediately after filling so the cucumber stays snappy and the avocado stays fresh and green.

Scoop the avocado flesh into a small mixing bowl. Add the lime juice, red onion, cilantro, cumin, salt, and black pepper. Mash and stir with a fork until the mixture is chunky but cohesive, with no large unbroken pieces of avocado remaining.
