Put sweet potato and water in a microwave safe bowl. Cover with plastic wrap. Microwave for 4 minutes, or until potatoes are tender. Remove plastic wrap (be careful - the steam is very hot!) and drain potatoes. Dry on paper towels.
In a nonstick skillet, heat oil over medium high heat. Add onion, bell pepper, microwaved potatoes, spices and 1 dash of salt. Cook until peppers are soft, about 5 minutes, stirring occasionally.
Add pineapple. Cook, stirring occasionally, until pineapple is warmed.
Mash avocado with juice from 1/2 the lime. Add 1 dash of salt. Cut remaining half of lime into 4 wedges.
Serve 1 cup hash with 1 egg (cooked to your preference), 2 tablespoons mashed avocado and lime wedge. Enjoy!
