I just can’t do it guys.

Nope. No way. No how.

You can dress it up all you want… smother it in bbq sauce, hide it in a quesadilla, pound it into a burger….

Okkkk maybe mold it into a McNugget…

But I cannot eat chicken again this week. I have hit my poultry limit. Do you ever get like that??

I don’t eat red meat and I’m usually too lazy to defrost frozen fish so my weeknight meals usually revolve around chicken.

Which I honestly don’t mind most of the time…but today I do. I am avoiding that little package of chicken boobies like the plague.

Like all of my favorite meals – this is so easy and quick to make. If I got a quarter for every I’ve used those two adjectives in my posts over the past couple weeks… I would probably have a dollar. Shoot.

This salmon salad is 2 steps – roast salmon in oven and whisk together dressing… Ooo the dressing! I love this dressing. Its a red-wine vinegar dressing mixed with salty capers and sweet red onions. Those flavors mixed with the buttery roasted salmon and soft bitter mixed greens is delish!

– And for those of you that don’t like capers; neither do I. Hate them. Love this dressing. For some magical reason this just totally works.

Add a squeeze of lemon juice over warm salmon for brightness and balance.

Serving & Storage : Store leftovers separately: keep salmon, dressing, and salad greens in different containers to prevent sogginess.
