In a medium saucepan, combine quinoa and broth and bring to a boil over medium-high heat. Reduce heat to low, cover and simmer for 10-12 minutes or until all broth is absorbed. Remove from heat.
Meanwhile, cook bacon in a skillet over medium-high heat until crisp. Remove from pan, crumble and set aside.
Reduce skillet heat to low, add red pepper flakes and minced garlic to the bacon grease and cook until garlic is softened about 3 minutes. Add in shrimp and cook until pink and opaque, about 3 minutes. Remove from heat, stir in lemon juice.
Add cheddar, salt and pepper to the quinoa and stir until all cheese is melted.
Plate by spooning half of quinoa in a bowl, topping with half the shrimp and sauce and sprinkling half the green onions and crumbled bacon on top.
Notes
*Note: Thick-cut bacon is the best choice because it gives you enough bacon grease to saute the remaining ingredients, but regular bacon would work too. Just use three slices instead of two.
