In a large skillet over medium-high-heat, add 2-3 tablespoons oil & heat till shimmering but not burning.
Add white-parts of onions and a few of the green-parts and saute a a few minutes or till just tender.
Add garlic and saute about 30minutes or till aromatic.
Add peppers and saute for 3-4minutes before beginning to get tender. Add broccoli and cook another 2-3minutes. Cook more longer for softer vegetables.
Add a few spoonfuls of General Tso's sauce into the sauteed veggies and stir to blend. Heat for 2-3minutes till warm when the sauce is not overly warm.
Spoon vegetables to a bowl & put aside.
Add chickpeas to the same saute-pan & over medium-heat, saute for 2-3minutes to heat.
Spoon General Tso's Sauce on the chickpeas, stir to blend and let simmer a couple of minutes and serve. The more the chickpeas simmer together with the sauce, the longer they absorb the taste.
Serve veggies and chickpeas. Garnish with sesame-seeds & extra green-parts of onion if desired.
