Mushroom Sandwich Melts

Ingredients:
1 medium onion, diced
3 garlic cloves, pressed
2 Tbsp butter
24 oz (1 1/2 lbs) white mushrooms, diced
8 oz turkey bacon, chopped into thin strips
2 Tbsp mayo
1/4 to 1/2 tsp salt, or to taste
1/4 tsp black pepper, or to taste
2 1/2 cups (8oz) Mexican cheese blend, finely shredded
1/4 cup fresh chopped parsley, plus more for garnish
2 soft French baguettes, sliced into 1/2″ thick toasts
Instructions:
Preheat oven to 350˚F and line a large baking sheet with parchment paper.
Heat a large non-stick skillet over medium heat. Add 1 Tbsp butter and chopped onion. Saute, stirring often, until soft and lightly golden (5-7 minutes). Add garlic and stir until fragrant (1 minute). Transfer to a mixing bowl.
In the same skillet over medium/high heat, add 1 Tbsp butter and saute mushrooms until soft, juices are released, and evaporated (10-12 minutes). Transfer mushrooms to the mixing bowl.
Add turkey bacon to the same skillet and sauté until browned (7 minutes). Transfer to a paper towel-lined plate to drain fat before adding to the mixing bowl.
Add 2 1/2 cups shredded cheese, 1/4 cup chopped parsley, 2 Tbsp mayonnaise, 1/4 to 1/2 tsp salt, and 1/4 tsp pepper to the mixing bowl. Stir to combine.
Spoon generously onto toasts, using the spoon to mound and shape the mixture. Bake at 350˚F for 15 minutes. Garnish with more fresh parsley if desired and serve warm.
