For the satay sauce: Whisk the peanut butter, coconut milk, lime juice, soy sauce, brown sugar and crushed red pepper together in a small bowl. Set aside.
For the sandwiches: Combine the peanut butter, chili powder, cumin, crushed red pepper and salt in a small bowl. Stir well.
On a nonstick baking sheet, lay out 4 slices of the brioche and spread with the spicy peanut butter. Top each slice with about 3 slices of the cheese. Broil until the cheese is melted, about 2 minutes.
Close the sandwiches with the remaining brioche and broil again until the top slices are toasted, about 1 minute--watch closely, as broilers vary. Flip the sandwiches on the baking sheet and broil one more time until the top slices are toasted, about 1 minute. Cut the sandwiches into triangles, drizzle with the satay sauce and serve.
