Preheat the oven to 425 degrees. Arrange veggies on a large sheet pan. Toss with olive oil and salt. Roast for 25-30 minutes.
In a large bowl, combine roasted veggies with the black beans, 1 cup quesadilla cheese and 1 cup enchilada sauce. Stir / gently mash to make a chunky filling.
Spread some enchilada sauce on the bottom of a 9×13 pan. Roll filling into tortillas, and place them seam-side down in the pan. Cover with remaining sauce and cheese.
Cover with foil and bake for 15-20 minutes, until bubbly and hot. Serve with avocado slices, cilantro, and a squeeze of lime! And settle in for some cozy Tex-Mex veggie goodness.
