How to make marinated onions
Marinating onions helps to take out the bitter punch from the onions and makes them almost sweet and the perfect addition to any salad! I use equal parts olive oil and red wine vinegar and add in salt and dried oregano.
In a bowl combine equal parts olive oil and red wine vinegar (3 tablespoons of each). Add in 1 tsp dried oregano and ½ teaspoon of salt.
Thinly slice 1/2 of a red onion. Add the red onion slices to the olive oil and red wine vinegar mixture. Allow the onions to marinate while the spaghetti squash is cooking.
