Beef, Quinoa & Red Pepper Power Bowl
A seared lean-sirloin bowl over quinoa with red pepper, spinach, and a squeeze of lemon — built so the vitamin C helps your body absorb the iron.

This is the kind of dinner that comes together in one skillet on a weeknight and still feels like a proper meal. Everything on the plate is here for a reason: the beef, the pepper, the lemon, and the greens all work together.
Why it helps
Lean beef supplies heme iron, the form your body absorbs most readily, while quinoa and spinach add plant-based non-heme iron. Pairing them with the vitamin C in red bell pepper and lemon meaningfully increases how much of that non-heme iron you actually absorb. One practical note: tea and coffee contain tannins that blunt iron absorption, so it helps to enjoy them an hour or two away from an iron-focused meal rather than alongside it.
Ingredients
- 1/2 cup dry quinoa, rinsed
- 1 cup low-sodium beef broth or water
- 8 oz lean sirloin steak (or 90% lean ground beef)
- 1 large red bell pepper, sliced
- 2 cups packed baby spinach
- 1 tablespoon olive oil
- 2 cloves garlic, minced
- 1 teaspoon ground cumin
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- Juice of 1/2 lemon
- 1/4 cup chopped fresh cilantro or parsley
Instructions
- 1Combine the rinsed quinoa and broth in a small saucepan. Bring to a boil, then reduce to a low simmer, cover, and cook 15 minutes until the liquid is absorbed. Fluff with a fork and set aside.
- 2Pat the steak dry and season both sides with the cumin, smoked paprika, salt, and black pepper.
- 3Heat the olive oil in a skillet over medium-high. Sear the steak 3 to 4 minutes per side for medium, then transfer to a board and rest 5 minutes before slicing thinly against the grain.
- 4In the same skillet, add the garlic and sliced red pepper. Saute 4 to 5 minutes until the pepper is crisp-tender.
- 5Add the spinach and toss just until wilted, about 1 minute, then remove from heat.
- 6Divide the quinoa between two bowls and top with the pepper-spinach mixture and sliced beef.
- 7Squeeze the lemon over each bowl, scatter with cilantro, and serve right away.

Tips & swaps
- Swap the sirloin for 90% lean ground beef, or use lentils plus an extra handful of spinach for a plant-based version that leans on the vitamin C to boost absorption.
- Cook a double batch of quinoa ahead and refrigerate up to 4 days; the assembled bowls also reheat well for next-day lunch.
- Keep the lemon fresh and add it right before eating — the vitamin C works best raw, so squeeze it on at the table rather than cooking it in.
- No cilantro fan? Flat-leaf parsley brings its own vitamin C and a cleaner, grassy note.
