Xanthan Gum Free Whole30 Cucumber Avocado Cups
These little cucumber cups are the kind of appetizer that disappears from the platter before you even sit down. Each crisp round gets hollowed into a natural vessel, then loaded with a chunky, lime-bright avocado filling packed with red onion, cilantro, and a whisper of cumin. The jalapeño and red pepper flakes are optional, so you can dial the heat up or down depending on your crowd. Because every ingredient here is whole and unprocessed, there's zero need to scan labels for hidden additives or stabilizers — no gums, no fillers, just real food. The lime juice keeps the filling fresh and punchy, while the cucumber provides a satisfying cool crunch that plays perfectly against the creamy avocado. These come together fast and require no cooking whatsoever, making them an ideal last-minute snack or starter. Serve them immediately for the best texture, with extra lime wedges on the side for anyone who wants an extra hit of brightness.
