In a small glass jar, whisk together the lemon juice, lemon zest, Dijon mustard, garlic powder, sea salt, and black pepper to create the zesty dressing.
Place the plant-based chicken strips in a bowl and toss with the avocado oil and one tablespoon of the prepared dressing.
Preheat a grill pan or outdoor grill to medium-high heat and grill the chicken strips for 3-4 minutes per side until deeply charred and heated through.
While the chicken grills, chop the romaine lettuce, halve the cherry tomatoes, and thinly slice the red onion.
In a large serving bowl, combine the chopped romaine, tomatoes, and red onion.
Top the greens with the hot grilled plant chicken, then sprinkle evenly with hemp hearts and nutritional yeast for a boost of protein and savory flavor.
Drizzle the remaining dressing over the salad and toss thoroughly before serving.
