This Keto Croque Monsieur is a low-carb version of the classic French sandwich. It features layers of ham, cheese, and a creamy sauce, all sandwiched between slices of keto-friendly bread. The sandwich is then toasted until the cheese is melted and bubbly, creating a deliciously crispy exterior. It's a satisfying and indulgent meal that is perfect for those following a keto or low-carb diet.
