How to Make Low Carb Marinated Green Beans and Tomatoes
Step 1: Cook the Green Beans
Start by placing the green beans in a large pot. Add enough water to cover them completely. Turn on the heat to high until the water begins to boil. Cover the pot and let them cook for about 8 to 10 minutes. You want them tender yet still crisp. This step ensures that your green beans have that delightful crunch when you bite into them!
Step 2: Ice Bath Time
Once they are cooked, carefully pour the beans into a strainer to drain the hot water. Then quickly transfer them into a bowl filled with ice water. This helps cool them down fast while keeping their vibrant color and crispness intact. After they’re cooled off, drain them again and place them into a large bowl.
Step 3: Whisk Together the Marinade
In a small bowl, mix together olive oil, lemon juice, balsamic vinegar, garlic, mustard, salt, and pepper. This dressing brings everything together beautifully! Pour this flavorful marinade over your green beans along with the diced onion.
Step 4: Marinate
Give everything a good mix so that every piece is coated with that zesty dressing. Cover the bowl with a lid or plastic wrap and pop it in the refrigerator for at least one hour or overnight if you have time. Allowing it to sit lets all those delicious flavors meld together.
Step 5: Finish with Tomatoes and Feta
Right before serving, take your marinated salad out of the fridge. Add in those halved grape tomatoes and crumbled feta cheese. Give everything one last gentle mix so it’s well combined. Now you’re ready to enjoy this colorful Low Carb Marinated Green Beans and Tomatoes salad!
