"Try this pastrami sandwich, dubbed the 'Hot Pat,' because of the healthy dose of spicy mustard in the filling and spread on the bread. It's loaded with warm mixture of pastrami, sauerkraut, and cabbage."
Heat oil in a large pot or Dutch oven over medium heat; cook and stir cabbage and garlic basil spread until cabbage begins to soften, about 5 minutes. Add sauerkraut, sweet hot mustard, and pastrami; cook and stir until hot, 3 to 4 minutes. Stir in 2 cups shredded Swiss cheese and cook until melted, 2 to 3 minutes.
Spread each hoagie bun with 1 tablespoon spicy brown mustard. Top with 4 slices Swiss cheese and evenly distribute the pastrami mixture among the sandwiches. Sprinkle with diced onion and top with tomato wedges.
