In a medium bowl, whisk together the olive oil, red wine vinegar, honey, lemon juice, and garlic. Season to taste with salt and pepper.
For the salad:
Slice the chicken breasts in half lengthwise to allow for faster cooking. Place the chicken pieces in a medium saucepan in a single layer. Add just enough water to cover the chicken. Heat over medium heat until the water comes to a simmer; let simmer until the chicken is just cooked through, about 10 to 15 minutes.
Remove the chicken from the pot. Let cool completely then use hands to shred the chicken. Refrigerate in a covered bowl until ready to use.
Add the bacon to a medium sauté pan over medium heat, and cook, until the fat has rendered and the bacon is crispy, about 5 minutes. Remove the bacon to a paper towel-lined plate to drain.
Add the chard, frisée, radicchio and fennel to a large salad bowl. Using tongs or serving spoons, toss the salad greens with the vinaigrette, adding a little at a time so the greens are evenly and lightly coated.
Add the bacon, pistachios and chicken, continuing to toss until all ingredients are combined. Top with the shaved truffle Gouda cheese and serve immediately.
Notes
If you can’t find truffle gouda, try shaved Parmesan, aged gouda, or even a creamy goat cheese.
