Mustard Free Whole30 Cucumber Avocado Cups
These little bites are proof that simple ingredients can make a genuinely impressive spread. Cool, crisp cucumber rounds get hollowed into natural cups and loaded with a chunky, bright avocado filling seasoned with lime juice, cumin, red onion, and fresh cilantro. The result is creamy, zesty, and just a little punchy — especially if you go for the optional jalapeño and red pepper flakes. For anyone navigating mustard-free eating, this recipe is completely stress-free: every ingredient is clean and straightforward, with zero condiments or spice blends that might sneak in hidden mustard. It also happens to be Whole30-compliant, so it works beautifully as a party appetizer or a light snack when you're keeping things tight. Serve them right away so the cucumber stays crisp and the avocado filling holds its fresh, vibrant color.
