Place a large skillet over medium-high heat and add in the bacon. Cook the bacon until crispy, about 7 minutes. When done, set aside on a paper towel lined plate and once cool enough to handle, crumble.

While the bacon cooks, place the green beans in a steamer basket and steam until crisp tender. Once the beans are done, turn off the heat and using tongs, transfer to a bowl of ice. Immediately add in the bell peppers to the steamer basket and just let steam in remaining heat (no need to turn the heat back on.)

Meanwhile, prepare the dressing. Combine all the olive oil, lemon juice, mustard, and honey in the bottom of a large mixing bowl, season with salt and pepper, and whisk together. Set aside.

Once everything is done cooking (green beans, bell peppers, and bacon), add them to the bowl with the prepare dressing and toss well. Add the feta and toss once more. Serve.
