4 slices good-quality whole wheat or sourdough bread, toasted
1 ripe avocado, peeled, cored and sliced
2 sweet onions, sliced into thin half-moons
2 large eggs, poached, fried or scrambled
3 tablespoons butter, divided
Salt and pepper, to taste
Make the caramelized onions: Heat a large skillet to medium and add two tablespoons butter. Add onions and sauté, stirring occasionally, until they are softened and turn a caramel-colored brown. This process should take about 30 minutes. Season with salt and pepper and remove from heat.
To assemble sandwiches, place two slices of toasted bread on a work surface and butter the side that is face up. Place one egg (or half of the scrambled eggs) and half of the avocado on each sandwich. Top with a spoonful of onions. Butter one side of each of the two remaining bread slices, place on top of sandwiches. Eat and enjoy!
