Place cream cheese in a large bowl. Use a hand mixer and mix on high for a couple of minutes until its glossy.
Add green onions, Worcestershire sauce, parsley, oregano, garlic powder, salt and pepper and mix on medium until fully combined.
Add cheddar cheese and mix on low-medium until combined.
Take half of the cream cheese mixture and form it into a ball shape.
Place walnuts on a place, making sure there is a mono-layer of walnuts.
Roll the cream cheese ball over the walnuts until it's fully covered.
Wrap the cheese ball with plastic wrap and place it in the fridge for 1 hour. Repeat with the other cheese ball.
Unwrap your cheese ball and let it soften for about 10 minute before serving.
Serve your cheese ball with crackers or thin bread for your guests.
