Torta Ahogada (Drowned Beef Sandwich)

Mr. Picky Eater claimed this to be the best sandwich he has had in the US. This is one good sandwich! You can adjust the heat to your taste by cutting back on the chipotles, or adding extra like I did. The recipe makes extra sauce so you may want to cut it in half, freeze some for later or leave it thick and serve some with chips. I'd also suggest adding extra avocado, cause it tastes so good.

Ingredients

• For the sauce

• 1 (10 ounce) can  chopped tomatoes with diced green chilies
• 2 (8 ounce) cans tomato sauce
• 1⁄4 cup  chopped fresh cilantro leaves
• 2 -3  chipotle chiles in adobo, seeded and chopped
• 2  teaspoons adobo sauce, from canned chipotles
• 1  lime, juiced
• 1  teaspoon kosher salt
• 1  cup low sodium beef broth

• For the meat filling

• 2  tablespoons  vegetable oil
• 1  large onion, thinly sliced
• 4  garlic cloves, minced
• 2  jalapenos, seeded, ribbed, and minced
• 1  lb  deli-sliced roast beef, cut into strips
• 1  avocado, halved, pitted, peeled and smashed
• 4  bolillo  ciabatta or 4  other crusty  sandwich buns, halved and lightly toasted

Directions

1. To prepare the sauce: In a large saucepan over medium heat, combine the chopped tomatoes with chiles, tomato sauce, cilantro, chipotles, adobo sauce, lime juice, and salt. Bring to a simmer, stirring. Reduce the heat to medium-low and continue to gently cook for 15 minutes, stirring occasionally.
2. To prepare the meat filling: Place a large skillet over medium-high heat and add the oil. When the oil is hot, add the onions. Cook and stir until the onions begin to soften, about 3 minutes. Add the garlic and jalapeno, stirring to incorporate. Cook and stir for an additional 2 to 3 minutes, until the onions are well browned and the garlic and jalapenos soften. Add the meat and toss until heated through and well combined, about 2 minutes. Add 3/4 cup of the tomato sauce to the roast beef mixture, tossing to coat.
3. Remove the sauce from the heat and add the broth. Using an immersion or standard blender, puree the sauce until smooth, it should be thin. Ladle the sauce into 4 bowls for dipping. Be sure the bowls are large enough so the sauce doesn't slop out when the sandwich is dipped.
4. To serve: Spread the smashed avocado on the both side of the roll. Pile the meat filling on the bottom halves of the sandwich buns, close, and cut each sandwich in half. Arrange each sandwich on a plate with the dipping sauce on the side. Dip and eat!
