Prepare the Garlic Bread:
Preheat your oven to 375°F (190°C).
In a small bowl, mix together the softened butter, minced garlic, Parmesan cheese, and parsley.
Spread the garlic butter mixture evenly on each half of the French bread.
Place on a baking sheet and bake for 10-12 minutes, or until the edges are golden and crispy.
Cook the Shrimp:
Heat olive oil in a skillet over medium heat.
Season the shrimp with salt, pepper, and paprika.
Cook the shrimp for 2-3 minutes on each side, or until pink and cooked through. Remove from heat.
Assemble the Sandwich:
On one half of the garlic bread, layer the cooked shrimp and sprinkle with Monterey Jack cheese.
Place the other half of the bread on top, and press down gently to adhere.
Heat a skillet over medium heat and add a bit of butter.
Carefully place the sandwich in the skillet and grill until the cheese is melted and the bread is toasted, about 3-4 minutes per side.
Cut into portions and serve hot.
