Four Bean Salad

This falls under the category of retro recipes but I still like it.  It’s great to take to a barbecue or a picnic.
Ingredients

• 1 can green beans
• 1 can green peas
• 1 can baby lima beans
• 1 can kidney beans
• 1 can of white corn
• 1/4 cup of sliced red onion
• 1-1/2 cups of chopped celery
• 1 small bell pepper, diced small
• 1/2 tablespoon of kosher salt
• 1 cup of granulated sugar
• 1 cup of apple cider vinegar
• 1/2 cup of canola or vegetable oil 
• 1 teaspoon of paprika
• 1/4 teaspoon of freshly cracked black pepper, or to taste

Instructions
Drain and combine the green beans, peas, lima beans, corn, red onion, bell pepper, celery and salt; cover and refrigerate for 1 hour. Drain off any accumulated liquid. In a separate container, whisk or shake together the sugar, vinegar, oil, mustard, paprika and pepper; pour over salad, toss and return to the refrigerator for several hours or overnight.
