Shellfish Free Whole30 Cucumber Avocado Cups
These little bites are the kind of appetizer that disappears from the platter before you even get a chance to announce them. Cool, crisp cucumber rounds act as the vessel for a bright, chunky avocado filling seasoned with lime juice, red onion, cilantro, and a whisper of cumin — fresh, vibrant, and genuinely satisfying. Because every single ingredient here is whole, plant-based, or naturally raised, there is zero guesswork about hidden additives or seafood-derived sauces sneaking into the mix. The jalapeño and red pepper flakes are optional, so you can dial the heat up or down depending on your crowd. Assembly is straightforward — hollow out the cucumber rounds, mash the filling, spoon and serve — which makes this a low-stress option for entertaining or a quick snack at home. Serve them immediately so the cucumber stays crisp and the avocado filling holds its gorgeous green color.
