1 medium-size yellow onion, chopped (about 1 1/2 cups)
2 tsp kosher salt, divided
2 large eggs, lightly beaten
1 (8-oz.) container sour cream
4 oz sharp Cheddar cheese, shredded (about 1 cup)

Instructions

Preheat the oven to 350°F (175°C).
Melt 2 tablespoons of butter in a large skillet over medium heat.
Add sliced yellow squash and chopped onion, cooking until tender. Season with 1 teaspoon of kosher salt.
