To prepare the dressing:

• Combine all ingredients in a 8 oz. mason jar (a bowl will work just fine too!).
• Cover with a lid and shake well to combine – if using a bowl, whisk until combined. Taste and adjust to your liking.
• If you’d like it to be a bit more acidic, add more vinegar. If it’s too acidic, add a little olive oil or even a teaspoon of maple syrup or honey. Set aside while prepping the salad. 
• To prepare the candied walnuts: 
• Roughly chop the walnuts and place in a medium frying pan. Pour in the maple syrup, sprinkle in a pinch of salt, and turn the heat to medium low. 
• Keeping a close eye on the mixture, stir gently as the maple syrup caramelizes on the nuts, about 5 minutes. Do not let them burn, it can happen quite quickly! 
• The nuts are ready when the syrup becomes sticky and coats the nuts like a thick caramel.
• Remove from heat, place the nuts in a small bowl or plate until ready to use.  
• Prepare the salad: 
• Heat a large skillet over medium high heat. Slice the Steak into strips about ½” thick. Use tongs to place the Steak strips on the frying pan, about 2 minutes. Then, flip each strip and cook until done, another 2-3 minutes more. 
• Once cooked, remove the Steak from heat and set aside until ready to use. 
• In a large salad mixing bowl combine feta, slivered onion, candied walnuts, Steak, and lettuce. 
• Drizzle the dressing over the top and toss well to combine.
