This recipe was my mom's and it's my favorite bean salad recipe because I grew up eating it. Funny how that matters. LOL
Very simple to make and makes enough to take to a picnic or potluck. Be sure to marinate it over night or for at least 6 hours.
In a large mixing bowl toss together drained beans, sliced onion rings and bell pepper rings.
In a separate medium mixing bowl whisk together Apple Cider Vinegar, Sugar, Salt, and Pepper until sugar and salt are mostly dissolved; add Vegetable Oil and continue to whisk until mixture is well incorporated.
Pour dressing over salad mixture and stir gently.
Refrigerate for 6 hours or overnight, stirring occasionally to ensure entire salad gets marinating time.
