Sunday's leftover steak, sliced over greens with feta. This is the Monday low carb lunch that makes Sunday dinner keep giving all week.
Slice the leftover steak thinly against the grain to preserve tenderness.
In a large salad bowl, combine the mixed greens, halved cherry tomatoes, and sliced cucumber.
In a small bowl, whisk together olive oil, red wine vinegar, dijon mustard, salt, and black pepper until the dressing emulsifies.
Drizzle the dressing over the salad and toss gently to coat all ingredients evenly without bruising the greens.
Top the salad with the sliced steak and crumbled feta, then serve immediately to enjoy optimal freshness and contrast in textures.
