Bring a medium pot of water to a boil.
Meanwhile, toast bread and pit and peel the avocado.
In a small bowl, lightly mash the avocado and mix in ¼ tsp (1 mL) smoked paprika. Divide among the 2 slices of bread and spread into an even layer. Top with 1-2 slices of tomato.
Once water is boiling, reduce to a simmer and stir in vinegar. Crack eggs into two small bowls. Create a whirlpool in the pot by stirring the water in one direction. Quickly, but carefully, pour the eggs into the water. Cook for 3-4 minutes for a soft yolk and 5 minutes for a firmer yolk. Once cooked to your desired doneness, remove egg and place on paper towel to absorb the water.
Place eggs on each piece of toast and sprinkle with remaining ¼ tsp (1 mL) smoked paprika and salt and pepper to taste.
