Heat 1 tablespoon butter and 2 tablespoons olive oil in a large skillet over medium-high heat.
Add the sliced onions, sprinkle with the sugar, and cook, stirring occasionally, until caramelized, about 10–12 minutes.
Stir in the sliced green bell peppers and cook until the peppers are tender, about 3–5 minutes; transfer the mixture to a bowl and set aside.
Return the skillet to medium-high heat and add the remaining 1 tablespoon butter and 1 tablespoon olive oil.
Add the thinly sliced tri-tip and cook, stirring occasionally, until browned, about 4–6 minutes.
Stir the Rondele garlic and herb spread (or cream cheese) into the cooked beef until combined, then remove from heat and let cool until warm, about 15–20 minutes.
Preheat the oven to 350°F and line a baking sheet with parchment paper.
Roll the pizza dough out into a rectangle on a lightly floured surface. Top the dough evenly with provolone slices, then spread the beef and vegetable mixture over the cheese.
Starting at one long edge, roll the dough into a tight log. Slice the log into 3/4-inch pinwheels.
Place the pinwheels on the prepared baking sheet about 2 inches apart and bake at 350°F until golden brown on top, about 9–11 minutes.
Remove from the oven and cool for 5–7 minutes before serving.
