I hate, seriously hate, ordering anything with zucchini at restaurants. For some reason, they can not cook it properly, and it always arrives mushy and nasty tasting. Every friggen' time.
Adding it at the tail end of the sautéing process helps eliminate that, and cooks it enough to be slightly chewy and that avoids the nasty taste of mushy squash.
This is a light side dish that does really well with white fish, on the side, or layered on top of the fish.

Stir in everything except the zucchini and yellow squash. Cook, while stirring for around 5 mimutes until everything starts to become tender. Add the zucchini and yellow squash. Cook for 2 to 3 minutes, until the zuchinni just starts to become tender. Serve with the lime sauce.
2 egg yolks 1 tablespoon lime juice 1/2 cup butter 1/2 tsp grated lime peel Place egg yolk and lime juice in a saucepan. Stir it with a wisk until well beaten. Add 1/4 cup of butter. Heat over low heat, stirring constantly. Add the rest of the butter. Beat the mixture as vigorously as you can until all of the butter is melted and the sauce thickens.
The butter in the lime sauce needs to heat slowly, else the butter will curdle.
Lots of other types of vegetables can be added or used as substitutes.
