Add olive oil to large skillet pan and heat over medium-high heat. Place veggie burgers, cut broccoli and diced green peppers in pan; cook until heated through, about 7-10 minutes (flipping burgers halfway). Set aside while making salad and dressing.
Distribute remaining vegetables (lettuce through carrots) evenly between two bowls.
Make dressing by combining remaining ingredients (kefir through black pepper) to a Mason jar or cup with lid. Shake until well-combined.
Top each salad bowl with a burger and sauteed veggies. Drizzle with kefir dressing and enjoy.
