    What Is Marinated Cucumber, Tomato & Red Onion Salad?

    Growing up my mom would slice a fresh cucumber from the garden and put them in a tubberware bowl with white vinegar and salt and pepper.  We loved eating those vinegar-y cucumber slices.  This salad is a modern take on that classic dish.  We've amped up the flavor with a homemade vinaigrette, and added lots of yummy seasonal veggies.

    What's The Grocery List?

    I love all of the fresh ingredients in this dish!  You'll need:

    • 3 cucumbers
    • 3 avocados
    • 4 roma tomatoes
    • 1 red onion
    • fresh dill
    • rice vinegar
    • olive oil
    • season salt
    • onion salt
    • garlic salt
    • black pepper
    • dried oregano

    How Do I Make This Marinated Cucumber, Tomato & Red Onion Salad?

    1. Chop your veggies.  You can do this one of two ways - chop everything large.  Or dice everything.  Both are delicious.  For this pictures I chopped everything large.
    2. Combine all veggies in a large bowl.
    3. In a blender jar - combine oil, vinegar, onion salt, garlic salt, season salt, black pepper, and oregano.
    4. Blend until emulsified.
    5. Toss dressing with veggies and refrigerate 30 minutes before serving.

    Pro Tip: Use a titan peeler for the easiest veggie pealing of your life!  One of my FAVORITE kitchen tools.

    Perfect For A BBQ

    This salad is really a crowd pleaser and is absolutely perfect for a potluck. May I suggest you serve this alongside of Lemon Lime Chicken, with a side of grilled potato salad, and topped off with Strawberry Shortcake?

    How To Choose Perfect Produce For This Salad:

    Cucumbers: Look for cucumbers with a bright, even colour of skin without dullness or sweating. The cucumber should look fresh. Choose a firm cucumber - firmness should be right through to the tips of the cucumber. Avoid cucumbers with blemishes, soft spots, yellowing, or easily bent.

    Tomatoes: The best tomatoes are completely free of bruises and should be a deep, bright red. Tomatoes that looks dull or pale are going to lack flavor. Avoid tomatoes with any discoloration - it could mean rot on the inside.

    Red Onion: choose a red onion that is heavy in your hand and firm to the touch. If an onion is soft or has a strong potent odor, then it has passed its peak.

    Avocados: Ripe avocados are typically a dark, almost black color. Squeeze the avocado gently- A ripe avocado should yield to firm, gentle pressure, but shouldn’t feel overly soft or mushy
