Step 1

Preheat the oven at 400 degrees.

Step 2

Meanwhile on the stovetop, brown the ground beef and diced onions over medium-high heat until fully cooked (about 8 minutes) and drain.

Step 3

Return the beef to the pan, and sprinkle on the taco seasoning.

Step 4

Stir in 3/4 cup water, bring it to a simmer, reduce heat and simmer until the liquid mostly evaporates, about 5 minutes.

Step 5

While the beef is cooking, add a generous layer of chips to two baking sheets lined with parchment paper.

Step 6

Spoon on refried beans, half on each pan. These are thick, but I just add spoon fulls all over the chips. (The spoon fulls will spread with the heat of the oven.)

Step 7

Spoon on half the ground beef to each pan of chips.

Step 8

Sprinkle shredded cheese on top.

Step 9

Bake at 400 degrees for 15 minutes.

Step 10

Remove from the oven, and sprinkle on diced tomatoes and green onions.

Step 11

Serve immediately.
