A quick and easy sandwich featuring creamy mashed avocado, juicy tomato slices, and fresh greens on a flaky toasted croissant with a hint of Dijon mustard for a subtle zing.
Toast croissant halves well to prevent sogginess. Pat tomato slices dry with a paper towel before assembling. Let avocado sit with lemon juice for a minute before spreading to enhance flavor and prevent browning. Optionally press sandwich in skillet after assembly to meld flavors.
