Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Propose three themed dinners and a waste-light grocery list for my family.

Questions to ask me first:
- Which cuisine theme and month/region for seasonal produce?
- Hard excludes (red meat, allergens) and starch limits?
- How many nights and leftover needs?

Inputs (fill in or confirm):
- Theme: [AMERICAN / MEDITERRANEAN / CAJUN / …]
- Region/month: [COLORADO / FEBRUARY]
- Excludes: [NO RED MEAT / …]
- Nights: [3+]

Rules:
- Each dinner needs protein, carb and vegetable.
- Reuse ingredients across meals.
- Return a full grocery list after the three ideas.
- Mark meals I may want to save to a favorites list.

Checkpoint: Show the three dinner names before the grocery list.

If you get stuck: If seasonal produce is unclear for my region, ask before substituting.

Verify before you finish: List has no duplicate impulse items and respects excludes.

Output: Three recipes plus one consolidated grocery list.

Done when: I can cook the plan and track whether the week stayed near my usual spend.
