The day before, make the marinade for the steak. Mix together spices. In a separate bowl, whisk together lime juice, vinegar, oil, and coconut aminos (or soy sauce). Add spices to create a sauce. Place steak in large dish or ziploc bag, and pour marinade over the steak. Marinate for at least 24 hours for best results.
The next day, heat up your grill. Grill steak for 5-8 minutes per side depending on thickness and preference for doneness. Brush peppers and onions with oil, and grill 5 minutes per side.
While steak and vegetables are grilling, prepare your salad dressing. Place all ingredients into a food processor or blender. Pulse until smooth adding additional water if needed.
Prepare your bowls. Line individual bowls or one large bowl with greens. Top with vegetables, steak, tomatoes, steak, extra pepitas, and dressing. Toss to combine.
