Farmers Market Weekends = The BEST Tomatoes!

The sun was shining yesterday when I opened my eyes, and I could already smell the coffee my husband was brewing. I love Saturday mornings that start like that, don’t you? One of my favorite things to do on a summer Saturday is wake up early, grab a cup of coffee, and head right to the Farmer’s Market. If you get there early enough, it’s still cool out and the vendors have their very best produce out for the choosing. I let my boys help choose some of the produce that we’ll take home, and they’re way more likely to eat something I make if they’ve been part of the process.

Farmers Markets with Kids:

The Farmer’s Market is a fun opportunity to teach kids about where food comes from. Farmers are actual people who live near us, and it’s cool to see them start to understand that. It’s also fun to teach them about the different produce available each season. I like giving each kid a job at the market. My 3 year old loves cucumbers, so he (very carefully and painstakingly to the point where I was like, “COME ON, KID!”) touched every single cucumber on the table before he finally chose two to take with us.

My oldest cares a little less about these things, so he was quick to pick out some heirloom tomatoes based solely on their color. If he liked the color, we got them. If he didn’t, he passed. I don’t think there’s such a thing as a bad summer tomato, so that worked just find for me! We got a few other things, too… fresh peaches from the orchard just 20 minutes away, some herbs, shallots, and more. Goodness, I love living close to farmland.

Fast Tomato + Avocado Salad

Once we got home, I was in full-on tomato salad mode. It’s probably the simplest summer dish you could ever make, because the tomatoes are totally the star. Everything else is just helping them shine! Pretty much whatever product you have in the kitchen will pair beautifully– you could add thinly sliced zucchini or summer squash, even fresh peaches would be a lovely addition. Here, I just slice a few tomatoes, an avocado, a cucumber and herbs, tossed everything with a quick balsamic vinaigrette, and bam, it’s a show-stopper.

I really can’t think of anything in the world that can beat summer tomatoes. They’re juicy, sweet, unbelievably fresh and flavorful, and I simply cannot get enough of them! I LOVE to take those beautiful tomatoes and eat them simply sliced with a little salt, or make something really special out of them — check out my Whole30 Bruschetta Salmon recipe! Pro-tip: Just before serving, sprinkle the entire salad with flakey sea salt. The tiny bit of salty crunch is an amazing surprise! You could prepare this whole salad in advance, letting the vegetables marinate in the vinaigrette. Just wait until just before you serve it to slice and add the avocado. You don’t want it to get brown and mushy!
