1. PREPARE THE INGREDIENTS
Wash and dry the fresh produce. Quarter the lime. Peel and thinly slice the garlic and onion. Remove and discard the papery husks of the tomatillos; medium dice the tomatillos. Drain and rinse the hominy. Pit, peel and medium dice the avocado; toss with the juice of 1 lime wedge to prevent browning. Trim off and discard the stem ends of the radishes; cut the radishes into matchsticks. Pick the cilantro leaves off the stems; discard the stems.
2. BROWN THE PORK
In a large pot, heat 2 teaspoons of olive oil on medium-high until hot. Add the ground pork; season with salt and pepper. Cook, frequently breaking the meat apart with a spoon, 3 to 5 minutes, or until lightly browned and just cooked through. Transfer to a bowl and set aside, leaving any drippings and browned bits (or fond) in the pot.
3. COOK THE AROMATICS & TOMATILLOS
Add 2 teaspoons of olive oil to the pot of reserved fond. Heat on medium-high until hot. Add the garlic, onion and all but a pinch of the spice blend; season with salt and pepper. Cook, stirring occasionally, 2 to 3 minutes, or until softened and fragrant. Add the tomatillos. Cook, stirring frequently and breaking apart the tomatoes with a spoon, 4 to 6 minutes, or until the tomatillos have softened and begun to thicken into a sauce.
4. FINISH THE SOUP
Add 2 cups of water to the pot of aromatics and tomatillos. Cook, stirring constantly and scraping up any browned bits from the bottom of the pot, 30 seconds to 1 minute, or until thoroughly combined. Add the hominy and browned pork; heat to boiling on high. Once boiling, reduce the heat to medium and simmer 7 to 9 minutes, or until slightly reduced in volume. Remove from heat. Stir in the juice of 1 lime wedge; season with salt and pepper to taste.
5. TOAST THE PEPITAS
While the soup simmers, in a small pan (nonstick, if you have one), heat 2 teaspoons of olive oil on medium-high until hot. Add the pepitas and remaining spice blend; season with salt and pepper. Cook, stirring frequently, 2 to 3 minutes, or until toasted and fragrant. (Be careful, as the pepitas may pop as they cook.) Remove from heat.
