Prepare the filling by peeling and mashing the avocados in a medium bowl until they reach your desired consistency—chunky or smooth.
Stir in the fresh lemon juice, pressed garlic, and minced onions.
Season with salt, taste, and adjust as needed.
Warm the corn tortillas one at a time in a dry skillet or directly over a gas flame for about 15-20 seconds per side, just until they are soft and pliable.
Working quickly, spread a heaping tablespoon of the avocado filling in a line across the lower third of a warm tortilla, then roll it up tightly.
Repeat with the remaining tortillas and filling.
Heat about ⅓ inch of vegetable oil in a large skillet over medium-high heat.
Once the oil is shimmering, carefully place the taquitos seam-side down in the pan, being careful not to overcrowd.
Fry for 2-3 minutes per side, until golden brown and crisp.
Transfer the fried taquitos to a paper towel-lined plate to drain excess oil. To serve, arrange the warm taquitos on a platter.
Garnish generously with a dollop of sour cream on each, a sprinkle of chopped onions, and a crumble of farmer cheese.
Serve immediately with your favorite Fresh Tomato Hot Sauce for dipping.
