Caramelized Onions.

These caramelized onions can be used to turn everything they adorn into gastronomic wonder. They are low calories flavor bombs to replace high-fat mayonnaise and spread for burgers, sandwiches, omelettes, or grilled meat.

Ingredients:

• 2 red onions, diced or sliced
• 1 tablespoons of balsamic vinegar
• 1 tablespoon olive oil or butter
• 1/4 to 1/2 tsp of salt
• black pepper to taste

Directions:

1. Heat up olive oil or butter in a sauce pan over medium heat.
2. Add the onions and 1/4 tsp of salt. Cook and stir every few minutes until all onions turn from translucent to light brown. This will take about 20 to 30 minutes. 
3. Add the vinegar and black pepper. Stir to mix evenly. Cook another 3 to 5 minutes.
4. Serve on sandwiches or meat. Keep the rest in containers or jars with tight lid. Refrigerate for up to 10 days.

Notes:

• Make a bigger batch to save the time. They can be kept in an air-tight container in the refrigerator for up to 10 days.
• Cook slowly on medium-low heat will give you the best results and flavor. If you are pressed for time,  you can raise the heat to medium and cook for shorter time.
