For best keto results, choose ham labeled with no added sugar and minimal carbs, and use full-fat cream cheese and real block cheese you shred yourself. The green onion and seasonings add flavor without significantly increasing carbs, but you can omit them for an ultra-simple version. These roll-ups travel well in lunchboxes or snack containers; keep them chilled with an ice pack if taking them on the go. Serve alongside crunchy low-carb veggies, olives, or pickles for a more complete snack or light meal.
