This turned out good-not-great, and I'd love to hear suggestions.

Here's what I did:
Sauteed 1/4 chopped onion and 3 chopped scallions in 2 tsp butter for a couple mins.
Added a medium tomato (coarsely chopped), 1/2 chopped avocado, handful of baby spinach leaves. Cooked for a couple mins.
Added 3 egg whites, 1 yolk (beaten with a bit of milk + salt and pepper).
When eggs set, stirred in broken up pieces of a TJ's whole wheat tortilla (toasted till almost burnt, then lightly buttered).
1. Eggs wound up extremely non-fluffy.
Due to the water content of the tomatoes?
2. Tomatoes a bit dry
To fix this and #1, maybe I should add fresh chopped tomato after cooking eggs, or at least much later in the process
3. Lack of scallion flavor
Maybe they're overwhelmed by the onions? Maybe I overcooked the onion/scallion combo?
4. Tortilla pieces too soggy
Guess I need to add them later. Or find a thicker bread to use, that can stand up better to the moisture.
