Easy Pasta with Cauliflower, Tuna & Pesto
Fifteen minutes between an empty pan and a 50g-protein dinner. Whole wheat penne coated in pesto, piled with steamed cauliflower and canned tuna, finished with a scattering of briny capers.
The cauliflower picks up flavor from the skillet while the pasta boils, so everything lands on the plate at the same time. Eight ingredients, one pan, 579 kcal.

Ingredients
- penne, whole wheat 3 ounces
- onion 0.25
- tuna, in water 5 ounces
- olive oil 0.5 tablespoon
- cauliflower florets 2 cups
- water 1 tablespoon
- capers 1 tablespoon
- pesto 2 teaspoons
Method
-
Prepare the pasta according to the instructions on the packaging.
-
Finely chop the onion. Drain the tuna in a strainer.
-
Heat the oil in a skillet and sauté the onion. Add the cauliflower florets with water. Steam the cauliflower until tender for 8 minutes. If needed, add a splash more water. Add the tuna and capers to the cauliflower and heat through.
-
Drain the pasta and save the cooking water. Mix the pesto with the warm pasta and optionally add some cooking water.
-
Serve the pasta with the cauliflower and tuna.
Save a splash of pasta cooking water before draining. The starch in that water helps the pesto emulsify and coat every piece of penne evenly, instead of clumping into green pockets.
Behind this recipe
Is 50g of protein in one meal too much?
The old 30g-per-meal ceiling has been overturned. Isotope tracer research tracked protein molecules through the body and found the system keeps working well beyond 30g — the cap was based on outdated measurement methods that stopped watching too soon. This bowl delivers 50g, mostly from canned tuna, and the body puts it to work.

Whole wheat penne contributes most of the 11g of fiber in this meal, alongside the cauliflower. Research has linked higher fiber intake to faster fat loss during calorie deficits — fiber increases satiety, feeds beneficial gut bacteria, and slightly reduces the calories the body absorbs from a meal.

Adding a small amount of water to a hot skillet creates a mini steam chamber. The cauliflower cooks through in 8 minutes without boiling (which would make it waterlogged) or roasting (which needs 25+ minutes). You get tender florets that still hold their shape — a hybrid technique that keeps the skillet meal on track.
