Happy Sunday, Friends!!

MOMS! HAPPY MOTHER’S DAY!! I hope you got to enjoy YOUR weekend!

When asked what I wanted for Mother’s Day, I said, sleep. That’s all I want. I want to SLEEP-IN! Like, don’t wake me up until this body wants to wake up on its own. Ya know what I mean?
WHO knew that the day I had kids was also the day I had to part with sleep. I miss that son of a gun!

However, since sleeping-in is not an option, because they WILL jump on my bed as soon as 6 a.m. hits, I jumped on Amazon and ordered myself a 3-hour house cleaning service aaaaaand a pair of shoes! Best presents, ever!

I am also looking forward to inhaling that Strawberries and Cream Ice Cream Cake that I made for myself. *happy*

So I made you taters! YAY!

Truly, this potato salad is SO awesome. It’s incredibly flavorful, the texture is amazing, and we LOVES IT! I think that’s all that matters. I wanted to spread the love, thus I’m sharing it with you!

The first time I made this salad, I was stoked! I love dijon mustard, and I will find a way to toss it/spread it on anything and everything. Also, potatoes love lots of flavor, and the mustard dressing delivers just that. The mushrooms and onions are the cherry on top. Finger-licking good. I promise.

You’re also going to find fresh thyme in there. YUMMERS! I love, love, love thyme! Check out my Savory Feta Cheese French Toast – all my thyme-love lives in that recipe.

    This potato salad is gorgeous! I don’t really care for the mayonnaise-y potato salads so this salad is perfect for me. Love that dijon vinaigrette! This salad would be perfect for summer BBQ’s! :) Pinned.

    Happy Mother’s Day, Kate! Sleeping-in makes a return in a few years. Believe me I am living it now. :-) The potatoes look so yummy and the pictures are CALLING my name. I haven’t even had a breakfast yet and all I want to do is to demolish those taters. I am a Dijon fanatic as well.
