How to Make Budget-Friendly Lentil & Veggie Stir-Fry

For the Lentils:

Rinse Lentils: Place lentils in a fine-mesh strainer and rinse under cold water until the water runs clear, removing any debris or dust.
Simmer Lentils: Transfer lentils to a saucepan, cover with broth, bring to a boil, then reduce to simmer. Cook 20 minutes until tender but not mushy.

For the Veggies:

Heat Sesame Oil: Warm sesame oil in a large skillet or wok over medium-high heat until shimmering and aromatic, about 1 minute as nutty notes emerge.
Sauté Aromatics: Add diced onion, minced garlic, and grated ginger to the skillet. Cook for 2–3 minutes, stirring often until fragrant and turning slightly golden.
Cook Vegetables: Stir in sliced bell peppers, julienned carrots, and broccoli florets. Sauté for 4–5 minutes, tossing frequently until crisp-tender and bursting with vibrant color.
Combine Lentils: Add the cooked lentils to the vegetable mixture, tossing gently to combine and coat every piece, ensuring even distribution of texture and flavor throughout the stir-fry.
Stir Sauce: Pour in soy sauce, lemon juice, and red pepper flakes. Stir for 2 minutes until sauce is fragrant and slightly reduced.
