Make the sauce. In a small bowl, whisk tamarind, fish sauce, brown sugar, soy sauce, chili-garlic sauce, and water.
Taste and adjust. You’re aiming for tangy, a bit sweet, and savory. Set aside.
Prep the noodles. Boil ramen for 1 to 1½ minutes—just until they start to loosen.
Drain immediately and toss with a teaspoon of oil to prevent sticking. They’ll finish in the pan.
Heat the pan. Set a large nonstick skillet or wok over medium-high heat. Add 1 tablespoon oil.
Sear the protein. Add shrimp, chicken, or tofu.
Season lightly with a pinch of salt. Cook until just done: shrimp turn pink and curl, chicken is no longer pink, tofu is lightly golden. Transfer to a plate.
Sauté aromatics. Add another tablespoon of oil.
Toss in garlic and the white parts of the scallions. Stir for 20–30 seconds until fragrant, not browned.
Scramble eggs. Push aromatics to one side. Add a little more oil if needed, then pour in the beaten eggs.
Let them set for 10 seconds, then scramble into soft curds.
Add noodles and sauce. Add the par-cooked ramen and pour the sauce over. Toss constantly for 1–2 minutes so the noodles soak up the sauce without breaking apart.
Finish with veggies and protein. Add bean sprouts, optional carrot/bell pepper, and the cooked protein. Stir-fry another minute.
Add the green parts of the scallions.
Serve and garnish. Plate it up. Top with chopped peanuts, extra chili, cilantro if using, and a generous squeeze of lime. Taste and adjust salt, sweetness, or tang right at the table.
