  • 1 tablespoon olive oil
  • 1 onion chopped
  • 4 cloves garlic minced
  • 1 pound zucchini trimmed and cut into ¾ inch dice
  • 1 pound yellow squash trimmed and cut into ¾ inch dice
  • 2 tablespoons fresh oregano minced, or 2 teaspoon dried
  • ½ teaspoon ground cumin
  • 1 cup corn kernels fresh or frozen (thawed)
  • 2 cups Monterey Jack Cheese finely shredded
  • 2 cups cheddar cheese finely shredded
  • 3 cups canned green enchilada sauce
  • 12 soft corn tortillas cut into 4 strips
  • 8 ounces queso fresco


  • Heat the oil in a skillet over medium-high heat. Add the onion and cook about 5 minutes. Add the garlic, zucchini, yellow squash, oregano, and cumin and continue to cook until vegetables start to brown, about 4 to 5 minutes. Add the corn, sauté for a minute or two and remove from the heat.
  • Mix the cheeses together. Pour about ½ cup of the enchilada sauce in the bottom of your slow cooker and spread it around. In layers add one-quarter of the tortilla strips, one-quarter of the enchilada sauce, one-third of the veggies, and one-quarter of the cheese blend and then sprinkle with one-quarter of the queso fresco. Repeat the layers, ending with the queso fresco. Your last layers will be tortillas, sauce and cheese (no veggies). Cover and cook on high for 2 hours or low for 4 hours.
  • Let cool for a few minutes before serving.
